如何從意圖視圖傳遞意圖附加信息Android

Question

對於ListView（我們可以在其中查找列表視圖的活動以及EditText）我使用的是AdapterView。

當我們點擊ListView我們去的第二個活動，我想發送所選項目作爲額外的數據在intent。這個數據，那麼將在EditText

顯示的一個元素

我試過這段代碼，但它似乎沒有工作，它總是顯示EditText的默認值。

這裏是適配器視圖的代碼：

public class adapterq extends ArrayAdapter<Questionaire> implements OnClickListener { 
    Bitmap image; 
     EditText name; 

    public adapterq(Context context, ArrayList<Questionaire> questionaires) { 
     super(context, 0, questionaires); 
    } 
    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // Get the data item for this position 
     final Questionaire c = getItem(position);  
     // Check if an existing view is being reused, otherwise inflate the view 
     if (convertView == null) { 
      convertView = LayoutInflater.from(getContext()).inflate(R.layout.customquest, parent, false); 
     } 

    View convertView2 = LayoutInflater.from(getContext()).inflate(R.layout.activity_main, parent, false); 


     TextView q = (TextView) convertView.findViewById(R.id.textView1); 
name =  (EditText) convertView2.findViewById(R.id.editText1); 


     q.setText(c.getLabel()); 

     convertView.setOnClickListener(this); 

     return convertView; 
    } 
    @Override 
    public void onClick(View v) { 
      Intent intent = new Intent(); 

      intent.setClass(getContext(), Questions.class); 

     intent.putExtra("name", name.getText().toString()); 
      getContext().startActivity(intent); 

    } 


} 

這裏是主要活動的XML代碼：

<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" 

tools:context="com.example.orange.v1.MainActivity" > 

<ListView 
    android:id="@+id/listView1" 
    android:layout_width="270dp" 
    android:layout_height="250dp" 
    android:layout_alignLeft="@+id/textView1" 
    android:layout_below="@+id/textView1" 
    android:isScrollContainer="false" 
    android:layout_marginTop="16dp" > 

</ListView> 

<TextView 
    android:id="@+id/textView2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignLeft="@+id/textView1" 
    android:layout_alignParentTop="true" 
    android:layout_marginTop="18dp" 

    android:text="User Identifier :" 
    android:textStyle="bold" /> 

<EditText 
    android:id="@+id/editText1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignLeft="@+id/textView2" 
    android:layout_below="@+id/textView2" 
    android:layout_marginTop="16dp" 
    android:text="Yass" 
    android:ems="10" > 

    <requestFocus /> 
</EditText> 

<TextView 
    android:id="@+id/textView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentLeft="true" 
    android:layout_below="@+id/editText1" 
    android:layout_marginLeft="21dp" 
    android:layout_marginTop="36dp" 
    android:text="Questionaire Choice" 
    android:textStyle="bold" /> 

<TextView 
    android:id="@+id/textView3" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignLeft="@+id/listView1" 
    android:layout_below="@+id/listView1" 
    android:layout_marginTop="26dp" 
    android:text="Select a category to start playing" />

如何從意圖查看的Android

因爲EditText是convertView2佈局內傳遞一個Intent額外但點擊監聽器是在convertView做得一樣：的onClick

q.setText(c.getLabel()); 
convertView.setOnClickListener(this); 
convertView.setTag(convertView2); 

使用v參數要獲得點擊EditText值的方法：

@Override 
    public void onClick(View v) { 
      Intent intent = new Intent(); 
      intent.setClass(getContext(), Questions.class); 
      View view=(View)v.getTag(); 
      EditText edtName=(EditText)view.findViewById(R.id.editText1); 
      intent.putExtra("name", edtName.getText().toString()); 
      getContext().startActivity(intent); 

    } 

Answer 2

更新您的代碼如下：

public class adapterq extends ArrayAdapter<Questionaire> implements OnClickListener { 
Bitmap image; 
EditText name; 

public adapterq(Context context, ArrayList<Questionaire> questionaires, EditText name) { 
    super(context, 0, questionaires); 
    this.name=name; 
} 
@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    // Get the data item for this position 
    final Questionaire c = getItem(position);  
    // Check if an existing view is being reused, otherwise inflate the view 
    if (convertView == null) { 
     convertView = LayoutInflater.from(getContext()).inflate(R.layout.customquest, parent, false); 
    } 

TextView q = (TextView) convertView.findViewById(R.id.textView1); 


    q.setText(c.getLabel()); 

    convertView.setOnClickListener(this); 

    return convertView; 
} 

@Override 
public void onClick(View v) { 
     Intent intent = new Intent(); 

     intent.setClass(getContext(), Questions.class); 

    intent.putExtra("name", name.getText().toString()); 
     getContext().startActivity(intent); 

} 

}

，並通過名稱的實例，同時初始化一個ArrayAdapter
