Android 扩展栅格视图和MClickListener

您好，我正在尝试从本机Gridview创建一个自定义Gridview，并覆盖onitemclick。但它从来没有捕捉到我自定义gridview上的点击

这是我的密码：

------自定义GridView类------

public class MyGridView extends android.widget.GridView implements AdapterView.OnItemClickListener {
private OnItemClickListener mListener;
public MyGridView(Context context) {
    super(context);
}

public MyGridView(Context context, AttributeSet attrs) {
    super(context, attrs);

}

public MyGridView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int heightSpec = heightMeasureSpec;
    if (getLayoutParams().height == LayoutParams.WRAP_CONTENT)
        heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >>2, MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, heightSpec);
}



@Override
public void setOnItemClickListener( OnItemClickListener l )
{
    System.out.println("MPIKA");
    mListener = l;
    super.setOnItemClickListener(this);
}




@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    System.out.println("test");
}


  }

  public class Store extends Activity implements MyGridView.OnItemClickListener {
   @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.stores);
    initialize();

}
 private void initialize() {

    openShops = new ArrayList<StoreClass>();
    closedShops = new ArrayList<StoreClass>();
    open = (MyGridView) findViewById(R.id.open);
    open.setOnItemClickListener(this);
     ......  
}

   /*
     @Override
       public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            AlertDialog.Builder builder1 = new AlertDialog.Builder(this,AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
        builder1.setMessage("Παρακαλώ επιλέξτε τύπο πακέτου");
        builder1.setCancelable(true);
        builder1.setPositiveButton("Ok",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                    }
                });

    AlertDialog alert11 = builder1.show();
    TextView messageText = (TextView)alert11.findViewById(android.R.id.message);
    messageText.setGravity(Gravity.CENTER);
    alert11.show();
}*/
}

------主类------

public class MyGridView extends android.widget.GridView implements AdapterView.OnItemClickListener {
private OnItemClickListener mListener;
public MyGridView(Context context) {
    super(context);
}

public MyGridView(Context context, AttributeSet attrs) {
    super(context, attrs);

}

public MyGridView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    int heightSpec = heightMeasureSpec;
    if (getLayoutParams().height == LayoutParams.WRAP_CONTENT)
        heightSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >>2, MeasureSpec.AT_MOST);
    super.onMeasure(widthMeasureSpec, heightSpec);
}



@Override
public void setOnItemClickListener( OnItemClickListener l )
{
    System.out.println("MPIKA");
    mListener = l;
    super.setOnItemClickListener(this);
}




@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    System.out.println("test");
}


  }

  public class Store extends Activity implements MyGridView.OnItemClickListener {
   @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.stores);
    initialize();

}
 private void initialize() {

    openShops = new ArrayList<StoreClass>();
    closedShops = new ArrayList<StoreClass>();
    open = (MyGridView) findViewById(R.id.open);
    open.setOnItemClickListener(this);
     ......  
}

   /*
     @Override
       public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            AlertDialog.Builder builder1 = new AlertDialog.Builder(this,AlertDialog.THEME_DEVICE_DEFAULT_LIGHT);
        builder1.setMessage("Παρακαλώ επιλέξτε τύπο πακέτου");
        builder1.setCancelable(true);
        builder1.setPositiveButton("Ok",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                    }
                });

    AlertDialog alert11 = builder1.show();
    TextView messageText = (TextView)alert11.findViewById(android.R.id.message);
    messageText.setGravity(Gravity.CENTER);
    alert11.show();

我尝试过这个，但没有工作

您是否看到任何日志消息？尝试使用log.dsomeTag，someMessage；而不是System.out.printlnsomeMessage；Syso正常：P问题是onclickListener，因为我使用自定义Gridview。你永远不知道！：P我觉得代码很正确。奇怪的是，甚至连MPIKA都没有印出来。如果自定义类或xml存在其他问题，则可能会出现NullPointerException或ClassCastException。。。但什么都没有
