多个ImageView 的 setOnTouchListener或setOnClickListener 不起作用

布局为：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
     <RelativeLayout
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
>
<ImageView android:id="@+id/imgmain"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" android:src="@drawable/cover1"/>
     <ImageView android:id="@+id/back"
                     android:layout_height="wrap_content"
                     android:layout_width="wrap_content"
                     android:src="@drawable/back"
                     android:layout_alignLeft="@+id/imgmain"
                     android:layout_alignTop="@+id/imgmain" android:paddingTop="40dip"  android:paddingLeft="26dip"/>
     <ImageView android:id="@+id/setup"
                     android:layout_height="wrap_content"
                     android:layout_width="wrap_content"
                     android:src="@drawable/setup"
                     android:layout_alignRight="@+id/imgmain"
                     android:layout_alignTop="@+id/imgmain" android:paddingTop="40dip"  android:paddingRight="24dip"/>
    <ImageView android:id="@+id/point1"
                     android:layout_height="wrap_content"
                     android:layout_width="wrap_content"
                     android:src="@drawable/point"
                     android:layout_alignRight="@id/imgmain"
                     android:layout_alignBottom="@id/imgmain" android:paddingBottom="52dip"  android:paddingRight="32dip"/>     
    <ImageView android:id="@+id/point2"
                     android:layout_height="wrap_content"
                     android:layout_width="wrap_content"
                     android:src="@drawable/setup"
                     android:layout_alignRight="@id/imgmain"
                     android:layout_alignBottom="@id/imgmain" android:paddingBottom="202dip"  android:paddingRight="32dip"/>                 
    <ImageView android:id="@+id/point3"
                     android:layout_height="wrap_content"
                     android:layout_width="wrap_content"
                     android:src="@drawable/back"
                     android:layout_alignRight="@id/imgmain"
                     android:layout_alignBottom="@id/imgmain" android:paddingBottom="202dip"  android:paddingRight="122dip"/>                             
    </RelativeLayout>  
</LinearLayout>程序为：
public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.point); 
        img_main = (ImageView) findViewById(R.id.imgmain);
        img_main.setImageResource(R.drawable.point_main);
             
        img_main.setOnClickListener(this);
        img_setup = (ImageView) findViewById(R.id.setup);
        img_back = (ImageView) findViewById(R.id.back);
        img_setup.setVisibility(View.INVISIBLE);
        //img_main.setOnClickListener(this);
        img_back.setOnClickListener(this);
        
        img_point1 = (ImageView) findViewById(R.id.point1);
        img_point2 = (ImageView) findViewById(R.id.point2);
        img_point3 = (ImageView) findViewById(R.id.point3);
        
        img_point1.setOnTouchListener(new OnTouchListener(){ 
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
//Toast.makeText(Point.this, "point_do_new1", Toast.LENGTH_SHORT).show(); 
         img_main.setImageResource(R.drawable.point_do_new1); 
     IsClick=1;
return false;
}});
        img_point2.setOnTouchListener(new OnTouchListener(){ 
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
//Toast.makeText(Point.this, "point_do_new1", Toast.LENGTH_SHORT).show(); 
         img_main.setImageResource(R.drawable.point_do_new2); 
     IsClick=1;
return false;
}});
        img_point3.setOnTouchListener(new OnTouchListener(){ 
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
//Toast.makeText(Point.this, "point_do_new1", Toast.LENGTH_SHORT).show(); 
         img_main.setImageResource(R.drawable.point_play_new1); 
     IsClick=1;
return false;
}});
          
    }
public void onClick(View v) {
// TODO Auto-generated method stub
if (v == img_back) { 
if (IsClick==0)
{
Intent intent = new Intent();// 得到一个意图的实例
intent.setClass(this, ViewPlay.class);// 设置当前activity以及将要操作的类
this.setResult(RESULT_OK, intent);
this.finish();
}
else
{
img_main.setImageResource(R.drawable.point_main); 
IsClick=0;
}
} 


}
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
return false;
}
问题就是 img_point1、img_point2、img_point3的onTouch 无论点击 哪个 都是最后一个起作用 也就是说 哪段代码 写在后面 就是哪段代码起作用
目前起作用的就是 img_point3.setOnTouchListener(new OnTouchListener(){ 
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
//Toast.makeText(Point.this, "point_do_new1", Toast.LENGTH_SHORT).show(); 
         img_main.setImageResource(R.drawable.point_play_new1); 
     IsClick=1;
return false;
}});img_point1、img_point2 事件 好像根本没有触发  有人知道是怎么回事吗？
