如何在android中的同一帧布局中获得两个重叠按钮的点击

现在我只是在每个按钮上放置onclick监听器,但它不能正常工作,每次只点击按钮两个工作.

请帮我找到解决方案.

这是我的@L_617_3@mainActivity.java代码.

package com.example.buttontest;

import java.util.Locale;

import android.app.Activity;
import android.os.bundle;
import android.util.Log;
import android.view.GestureDetector;
import android.view.GestureDetector.onGestureListener;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.onTouchListener;
import android.widget.button;
import android.widget.Toast;

public class MainActivity extends Activity implements OnGestureListener{
    private GestureDetector gestureDetector;


    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.activity_main);
        gestureDetector=new GestureDetector(this);

        Button b1=(Button)findViewById(R.id.button2);

        Button b2=(Button)findViewById(R.id.button1);

        b1.setOnTouchListener(new OnTouchListener() {

            public Boolean onTouch(View v,MotionEvent E) {
                int width = findViewById(R.id.button1).getWidth();
                int height = findViewById(R.id.button1).getHeight();
                float touchedX = e.getX();
                float touchedY = e.getY();
                Boolean inUpperTriangle = (height - touchedY) * width > touchedX * height;
                if(inUpperTriangle==truE)
                    Toast.makeText(getApplicationContext(),"upper",Toast.LENGTH_SHORT).show();

                if(inUpperTrianglE) gestureDetector.onTouchEvent(E);
                return inUpperTriangle;
            }

        });

        b2.setOnTouchListener(new OnTouchListener() {

            public Boolean onTouch(View v,MotionEvent E) {




                int width = findViewById(R.id.button2).getWidth();
                int height = findViewById(R.id.button2).getHeight();
                float touchedX = e.getX();
                float touchedY = e.getY();
                Boolean inLowerTriangle = (height - touchedY) * width < touchedX * height;
                if(inLowerTriangle==truE)
                    Toast.makeText(getApplicationContext(),"lower",Toast.LENGTH_SHORT).show();
                if(inLowerTrianglE) gestureDetector.onTouchEvent(E);
                return inLowerTriangle;
            }
        });




    }


    public Boolean onDown(MotionEvent E) {
        // TODO Auto-generated method stub
        return false;
    }


    public Boolean onFling(MotionEvent e1,MotionEvent e2,float veLocityX,float veLocityY) {
        // TODO Auto-generated method stub
        return false;
    }


    public void onLongPress(MotionEvent E) {
        // TODO Auto-generated method stub

    }


    public Boolean onScroll(MotionEvent e1,float distanceX,float distanceY) {
        // TODO Auto-generated method stub
        return false;
    }


    public void onShowPress(MotionEvent E) {
        // TODO Auto-generated method stub

    }


    public Boolean onSingleTapUp(MotionEvent E) {
        return true;
    }

}

我的布局文件是.

<FrameLayout xmlns:android="http://scheR_965_11845@as.android.com/apk/res/android"
android:id="@+id/FrameLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:BACkground="@drawable/button2" />

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:BACkground="@drawable/button1" />

请告诉我如何正确点击这两个按钮.

这是我的drawables.i使用黄色三角形作为按钮1图像,绿色作为按钮2图像.
