Android自定義列表視圖與ImageButton

有人可以幫我做到這一點嗎？當我點擊圖像按鈕加（+）顯示爲0的數值（textview）變爲1,2,3等。這是我的代碼

這是ListObat.java package co.id.zsoft.apotikstore;

import android.app.Activity; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.ListView; 
import android.widget.Toast; 

import java.util.ArrayList; 

public class ListObat extends Activity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_list_obat); 

     ArrayList<ItemDetails> image_details = GetSearchResults(); 

     final ListView lv1 = (ListView) findViewById(R.id.listView); 
     lv1.setAdapter(new ItemListBaseAdapter(this, image_details)); 

     lv1.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> a, View v, int position, long id) { 
       Object o = lv1.getItemAtPosition(position); 
       ItemDetails obj_itemDetails = (ItemDetails) o; 
       Toast.makeText(ListObat.this, "You have chosen : " + " " + obj_itemDetails.getName(), Toast.LENGTH_LONG).show(); 
      } 
     }); 
    } 

    private ArrayList<ItemDetails> GetSearchResults(){ 
     ArrayList<ItemDetails> results = new ArrayList<ItemDetails>(); 

     ItemDetails item_details = new ItemDetails(); 
     item_details.setName("Pizza"); 
     item_details.setItemDescription("Spicy Chiken Pizza"); 
     item_details.setPrice("RS 310.00"); 
     item_details.setImageNumber(1); 
     results.add(item_details); 

     item_details = new ItemDetails(); 
     item_details.setName("Burger"); 
     item_details.setItemDescription("Beef Burger"); 
     item_details.setPrice("RS 350.00"); 
     item_details.setImageNumber(2); 
     results.add(item_details); 

     item_details = new ItemDetails(); 
     item_details.setName("Pizza"); 
     item_details.setItemDescription("Chiken Pizza"); 
     item_details.setPrice("RS 250.00"); 
     item_details.setImageNumber(3); 
     results.add(item_details); 

     item_details = new ItemDetails(); 
     item_details.setName("Burger"); 
     item_details.setItemDescription("Chicken Burger"); 
     item_details.setPrice("RS 350.00"); 
     item_details.setImageNumber(4); 
     results.add(item_details); 

     item_details = new ItemDetails(); 
     item_details.setName("Burger"); 
     item_details.setItemDescription("Fish Burger"); 
     item_details.setPrice("RS 310.00"); 
     item_details.setImageNumber(5); 
     results.add(item_details); 

     item_details = new ItemDetails(); 
     item_details.setName("Mango"); 
     item_details.setItemDescription("Mango Juice"); 
     item_details.setPrice("RS 250.00"); 
     item_details.setImageNumber(6); 
     results.add(item_details); 


     return results; 
    } 


    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_list_obat, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
}

這是ItemDetails.java

package co.id.zsoft.apotikstore; 

/** 
* Created by rsr_unitedstate on 12/18/2015. 
*/ 
public class ItemDetails { 
    public String getName() { 
     return name; 
    } 
    public void setName(String name) { 
     this.name = name; 
    } 
    public String getItemDescription() { 
     return itemDescription; 
    } 
    public void setItemDescription(String itemDescription) { 
     this.itemDescription = itemDescription; 
    } 
    public String getPrice() { 
     return price; 
    } 
    public void setPrice(String price) { 
     this.price = price; 
    } 
    public int getImageNumber() { 
     return imageNumber; 
    } 
    public void setImageNumber(int imageNumber) { 
     this.imageNumber = imageNumber; 
    } 

    private String name ; 
    private String itemDescription; 
    private String price; 
    private int imageNumber; 
}

這是ItemListBaseAdapter.java

package co.id.zsoft.apotikstore; 

import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageButton; 
import android.widget.ImageView; 
import android.widget.TextView; 

import org.w3c.dom.Text; 

import java.util.ArrayList; 

/** 
* Created by rsr_unitedstate on 12/18/2015. 
*/ 
public class ItemListBaseAdapter extends BaseAdapter { 
     private static ArrayList<ItemDetails> itemDetailsrrayList; 

     private Integer[] imgid = { 
       R.drawable.testimage, 
       R.drawable.testimage, 
       R.drawable.testimage, 
       R.drawable.testimage, 
       R.drawable.testimage, 
       R.drawable.testimage 
     }; 

     private LayoutInflater l_Inflater; 

     public ItemListBaseAdapter(Context context, ArrayList<ItemDetails> results) { 
      itemDetailsrrayList = results; 
      l_Inflater = LayoutInflater.from(context); 
     } 

     public int getCount() { 
      return itemDetailsrrayList.size(); 
     } 

     public Object getItem(int position) { 
      return itemDetailsrrayList.get(position); 
     } 

     public long getItemId(int position) { 
      return position; 
     } 

     public View getView(int position, View convertView, ViewGroup parent) { 
      ViewHolder holder; 
      if (convertView == null) { 
       convertView = l_Inflater.inflate(R.layout.item_details_view, null); 
       holder = new ViewHolder(); 
       holder.txt_itemName = (TextView) convertView.findViewById(R.id.name); 
       holder.txt_itemDescription = (TextView) convertView.findViewById(R.id.price); 
       holder.txt_itemPrice = (TextView) convertView.findViewById(R.id.price); 
       holder.itemImage = (ImageView) convertView.findViewById(R.id.photo); 
       holder.txt_qty = (TextView) convertView.findViewById(R.id.Qty); 
       holder.btnkurang = (ImageButton) convertView.findViewById(R.id.btnkurang); 
       holder.btntambah = (ImageButton) convertView.findViewById(R.id.btntambah); 

       convertView.setTag(holder); 
      } else { 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      holder.txt_itemName.setText(itemDetailsrrayList.get(position).getName()); 
      holder.txt_itemDescription.setText(itemDetailsrrayList.get(position).getItemDescription()); 
      holder.txt_itemPrice.setText(itemDetailsrrayList.get(position).getPrice()); 
      holder.itemImage.setImageResource(imgid[itemDetailsrrayList.get(position).getImageNumber() - 1]); 
//  imageLoader.DisplayImage("http://192.168.1.28:8082/ANDROID/images/BEVE.jpeg", holder.itemImage); 

      return convertView; 
     } 

     static class ViewHolder { 
      TextView txt_itemName; 
      TextView txt_itemDescription; 
      TextView txt_itemPrice; 
      TextView txt_qty; 
      ImageView itemImage; 
      ImageButton btntambah; 
      ImageButton btnkurang; 
     } 
    }

這是activity_list_obat.xml爲列表視圖佈局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" 
    android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    tools:context="co.id.zsoft.apotikstore.ListObat"> 


    <EditText 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/editText" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" /> 

    <ImageButton 
     android:layout_width="70dp" 
     android:layout_height="70dp" 
     android:id="@+id/imageButton" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentEnd="true" /> 

    <ListView 
     android:layout_width="wrap_content" 
     android:layout_height="400dp" 
     android:id="@+id/listView" 
     android:layout_below="@+id/editText" 
     android:layout_alignParentEnd="true" /> 
</RelativeLayout>

而且這是item_details_view.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent"

     android:id="@+id/photo" 
     android:layout_alignParentTop="true" 
     android:layout_alignParentStart="true" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Nama Obat" 
     android:id="@+id/name" 
     android:layout_alignParentTop="true" 
     android:layout_toEndOf="@+id/photo" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Harga Obat" 
     android:id="@+id/price" 
     android:layout_below="@+id/name" 
     android:layout_toEndOf="@+id/photo" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Nama Apotik" 
     android:id="@+id/itemDescription" 
     android:layout_below="@+id/price" 
     android:layout_toEndOf="@+id/photo" /> 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="0" 
     android:id="@+id/Qty" 
     android:layout_below="@+id/itemDescription" 
     android:layout_toEndOf="@+id/photo" /> 

    <ImageButton 
     android:layout_width="20dp" 
     android:layout_height="20dp" 
     android:id="@+id/btnkurang" 
     android:layout_below="@+id/itemDescription" 
     android:layout_toEndOf="@+id/Qty" 
     android:src="@drawable/minus"/> 

    <ImageButton 
     android:layout_width="20dp" 
     android:layout_height="20dp" 
     android:id="@+id/btntambah" 
     android:layout_below="@+id/itemDescription" 
     android:layout_toEndOf="@+id/btnkurang" 
     android:src="@drawable/plus" /> 

</RelativeLayout>

嘗試這種方式它對我有用

mBTIncrement.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
        int mValue = Integer.parseInt(_value.getText().toString()); 
        mValue++; 
        _value.setText("" + mValue); 
       } 
      }); 

      _decrease.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 

        int mValue = Integer.parseInt(_value.getText().toString()); 
        mValue--; 

        if (mValue < 0) { 
         System.out.println("not valid"); 
        } else 
        { 
         _value.setText(""+mValue); 

        } 
       } 
      });

謝謝他們的作品！ – Shumimura

很高興幫助你..快樂編碼:) –

設置OnClickListener上holder.btnkurang和holder.btntambah內部適配器的getView方法。並相應地增加和減少holder.txt_qty的值。

holder.btnkurang.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       int qty = Integer.parseInt(holder.txt_qty.getText().toString()); 
       holder.txt_qty.setText(String.valueOf(qty-1)); 
      } 
     }); 

     holder.btntambah.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       int qty = Integer.parseInt(holder.txt_qty.getText().toString()); 
       holder.txt_qty.setText(String.valueOf(qty+1)); 
      } 
     });

持有人內onclicklistener錯誤「變量持有人從內部類訪問，需要聲明菲娜L」。當我改變持有人到最後，錯誤更改爲「無法解析符號getText」 – Shumimura

對不起我的mistake.its getText（）不getText.I將更新答案 –

@Shumimura看到我編輯的答案 –

在您的自定義適配器中更改您的getView方法。
你將不得不做一些其他的變化藏漢

public View getView(int position, View convertView, ViewGroup parent) { 
      ViewHolder holder; 
      if (convertView == null) { 
       convertView = l_Inflater.inflate(R.layout.item_details_view, null); 
       holder = new ViewHolder(); 
       holder.txt_itemName = (TextView) convertView.findViewById(R.id.name); 
       holder.txt_itemDescription = (TextView) convertView.findViewById(R.id.price); 
       holder.txt_itemPrice = (TextView) convertView.findViewById(R.id.price); 
       holder.itemImage = (ImageView) convertView.findViewById(R.id.photo); 
       holder.txt_qty = (TextView) convertView.findViewById(R.id.Qty); 
       holder.btnkurang = (ImageButton) convertView.findViewById(R.id.btnkurang); 
       holder.btntambah = (ImageButton) convertView.findViewById(R.id.btntambah); 

       //// add click listener here 
       holder.btnkurang.setOnItemClickListener(new OnItemClickListener() { 
        @Override 
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 
         /// change the price 
        } 
       }); 

       convertView.setTag(holder); 
      } else { 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      holder.txt_itemName.setText(itemDetailsrrayList.get(position).getName()); 
      holder.txt_itemDescription.setText(itemDetailsrrayList.get(position).getItemDescription()); 
      holder.txt_itemPrice.setText(itemDetailsrrayList.get(position).getPrice()); 
      holder.itemImage.setImageResource(imgid[itemDetailsrrayList.get(position).getImageNumber() - 1]); 

      return convertView; 
     }

我有三個圖像按鈕，我想當我點擊這個按鈕發送一些值到另一個活動。我用來切換案例給我的按鈕的指示。請幫助我，請幫助我，我該如何做這份工作。 –

只是需要一個靜態int變量記錄計數和一套標籤和gettag這樣調用後的ImageButton的clickListener在getview方法：

holder.btnkurang.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
     holder.txt_qty.setText(staticIntvariable-1); 
    } 
}); 
holder.btntambah.setOnClickListener(new View.OnClickListener() { 
    public void onClick(View v) { 
     holder.txt_qty.setText(staticIntvariable+1); 
    } 
});
