我的布局中有一个imageview和一个textview,我想用触摸移动这个imageview。它的工作,但问题是textview移动,你能告诉我如何解决它?

这是我的代码

private ImageView img;
private int status=0;
TextView tv;
RelativeLayout.LayoutParams params;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
     img=(ImageView)findViewById(R.id.imageView1);
     img.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent arg1) {
            // TODO Auto-generated method stub

            status=1;

        return false;
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_main, menu);

    return false;
}


@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub

    if( status==1)
    {
        LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        lp.topMargin=(int)event.getRawY();
        lp.leftMargin=(int)event.getRawX();
        img.setLayoutParams(lp);
    }
    if(event.getAction()==MotionEvent.ACTION_UP){
    status=0;
    }
return super.onTouchEvent(event);

} }

这是我的XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="84dp"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/imageView1"
    android:layout_alignParentTop="true"
    android:layout_marginTop="119dp"
    android:text="TextView" />
