android button在listview中可點擊

我有一個列表視圖。在列表視圖的每一行的佈局中，我有一個按鈕。該按鈕在xml中有一個「android：onClick =」onClickDoSmth「」。列表視圖也有一個itemClickListener。android button在listview中可點擊

在Activity類中，我有一個方法「public void onClickDoSmth（View v）」，它在按鈕被擊中時被調用。

但我也爲列表視圖設置了一個ItemClickListener。我希望當行（在按鈕之外）被擊中時去到另一個活動。當按鈕可見時，Listview的ItemClickListener不起作用。當按鈕是View.GONE時，那麼listview的偵聽器就可以工作。

有什麼建議嗎？

add android:descendantFocusability="blocksDescendants"作爲您的Button的財產。那麼你應該能夠同時管理onClickDoSmth/onListItemClick或itemClickListener

使用的ImageView代替按鈕。按鈕單擊和OnItemClickListener不能一起工作。

這裏是一個工作示例：

MainActivity.java 

public class MainActivity extends Activity { 
    private ListView customLV; 
    private CustomArrayAdapter adapter; 
    String strArray[] = { "First", "Second", "Third", "Forth", "Fifth" }; 
    ArrayList<String> strAL = new ArrayList<String>(Arrays.asList(strArray)); 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     customLV = (ListView) findViewById(R.id.customLV); 
     adapter = new CustomArrayAdapter(this, R.layout.list_item, strAL); 
     customLV.setAdapter(adapter); 
     customLV.setOnItemClickListener(new OnItemClickListener() { 

      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long arg3) { 
       Toast.makeText(getApplicationContext(), "List Item", Toast.LENGTH_SHORT) 
         .show(); 

      } 
     }); 
    } 

}

CustomArrayAdapter.java

public class CustomArrayAdapter extends ArrayAdapter<String> { 

    Context context; 

    public CustomArrayAdapter(Context context, int textViewResourceId, 
      ArrayList<String> strAL) { 
     super(context, textViewResourceId, strAL); 
     this.context = context; 

    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder viewHolder; 

     if (convertView == null) { 
      LayoutInflater inflater = (LayoutInflater) context 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

      convertView = inflater.inflate(R.layout.list_item, parent, false); 

      viewHolder = new ViewHolder(); 

      viewHolder.titleTV = (TextView) convertView 
        .findViewById(R.id.titleTV); 
      viewHolder.testBT = (ImageView) convertView.findViewById(R.id.testBT); 
      viewHolder.testBT.setOnClickListener(new OnClickListener() { 

       @Override 
       public void onClick(View v) { 
        Toast.makeText(context, "Button Clicked", 
          Toast.LENGTH_SHORT).show(); 
       } 
      }); 
      convertView.setTag(viewHolder); 
     } else { 
      viewHolder = (ViewHolder) convertView.getTag(); 
     } 
     viewHolder.titleTV.setText(getItem(position)); 

     return convertView; 
    } 

    class ViewHolder { 
     TextView titleTV; 
     ImageView testBT; 

    } 
}

list_item.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="10dp" > 

    <TextView 
     android:id="@+id/titleTV" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentLeft="true" /> 

    <ImageView 
     android:id="@+id/testBT" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentRight="true" 
     android:onClick="onClick" 
     android:src="@drawable/ic_launcher" /> 

</RelativeLayout>

activity_main.xml中

<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:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context=".MainActivity" > 

    <ListView 
     android:id="@+id/customLV" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
/> 

</RelativeLayout>
