组合控制：ImageButton和TextView，我想ImageButton可以响应点击事件，而不是TextView，但是，我不能这样做

Question

    package com.example.test20140308;

import android.content.Context;

public class MainButton extends LinearLayout {
    private Drawable drawable;
    private Drawable drawablebg;
    public ImageButton mImage;
    TextView mText;
    private int size;
    String text = "";

    public MainButton(Context context) {
        super(context);
    }

    public MainButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        TypedArray localTypedArray = context.obtainStyledAttributes(attrs,
                R.styleable.MyButton);
        if (localTypedArray.hasValue(R.styleable.MyButton_MyButtonIcon)) {
            this.drawable = localTypedArray
                    .getDrawable(R.styleable.MyButton_MyButtonIcon);
        }
        if (localTypedArray.hasValue(R.styleable.MyButton_MyBackground)) {
            this.drawablebg = localTypedArray
                    .getDrawable(R.styleable.MyButton_MyBackground);
        }
        if (localTypedArray.hasValue(R.styleable.MyButton_MyButtonSize)) {
            this.size = ((int) localTypedArray.getDimension(
                    R.styleable.MyButton_MyButtonSize, 0.0F));
        }

        this.mImage = new ImageButton(context, attrs);
        this.mImage.setImageDrawable(this.drawable);
        this.mImage.setAdjustViewBounds(true);
        this.mImage.setBackgroundDrawable(this.drawablebg);
        this.mImage.setLayoutParams(new LinearLayout.LayoutParams(
                getResources().getInteger(R.integer.imagebutton_w),
                getResources().getInteger(R.integer.imagebutton_h)));
        this.mImage.setClickable(true);
        this.mImage.setFocusable(true);


        this.mText = new TextView(context, attrs);
        this.mText.setPadding(0,
                getResources().getInteger(R.integer.padding_top), 0, 0);
        this.mText.setTextSize(this.size);
        this.mText.setTextColor(Color.rgb(81, 81, 81));
        this.mText.setGravity(1);
        this.mText.setClickable(false);
        this.mImage.setFocusable(false);
        setOrientation(1);
        addView(this.mImage);
        addView(this.mText);
        localTypedArray.recycle();
    }
}

我尝试使用ImageButton和TextView为我的应用程序创建组合控件，我希望ImageButton可以响应click事件而TextView没有.Howerer，当我尝试在我的应用程序中使用它时，我发现结果相反，只有当我触摸TextView时，组合控件才能响应。下面是我的活动代码：

package com.example.test20140308;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Toast;
public class MainActivity extends Activity {
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  MainButton buutonButton = (MainButton) findViewById(R.id.btnSavedetail1);
  buutonButton.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    Toast.makeText(MainActivity.this, "cc", Toast.LENGTH_LONG)
      .show();
   }
  });
 }
 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }
}

我的英语不够好，也许你会感到困惑，请指出来，谢谢！
