Here is the sample code.</p> <pre><code> /** Touchmoveimage.java*/ package com.examples.Touchmoveimage; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.MotionEvent; import android.view.View; import android.view.View.OnTouchListener; import android.widget.ImageView; import android.widget.LinearLayout.LayoutParams; public class Touchmoveimage extends Activity implements OnTouchListener{ int windowwidth; int windowheight; private LayoutParams layoutParams ; private LayoutParams layoutParams1 ; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); windowwidth = getWindowManager().getDefaultDisplay().getWidth(); windowheight = getWindowManager().getDefaultDisplay().getHeight(); ImageView ball= (ImageView)findViewById(R.id.ball); ball.setOnTouchListener(this); ImageView ball1 = (ImageView)findViewById(R.id.ball1); ball1.setOnTouchListener(this); } public boolean onTouch(View v,MotionEvent event) { switch(v.getId()) { case R.id.ball: ImageView ball= (ImageView)findViewById(R.id.ball); layoutParams = (LayoutParams) ball.getLayoutParams(); switch(event.getAction()) { case MotionEvent.ACTION_DOWN: break; case MotionEvent.ACTION_MOVE: int x_cord = (int)event.getRawX(); int y_cord = (int)event.getRawY(); if(x_cord&gt;windowwidth){x_cord=windowwidth;} if(y_cord&gt;windowheight){y_cord=windowheight;} layoutParams.leftMargin = x_cord -25; layoutParams.topMargin = y_cord - 75; ball.setLayoutParams(layoutParams); break; default : break; } case R.id.ball1: ImageView ball1= (ImageView)findViewById(R.id.ball1); layoutParams1 = (LayoutParams) ball1.getLayoutParams(); switch(event.getAction()) { case MotionEvent.ACTION_DOWN: break; case MotionEvent.ACTION_MOVE: int x_cord = (int)event.getRawX(); int y_cord = (int)event.getRawY(); if(x_cord&gt;windowwidth){x_cord=windowwidth;} if(y_cord&gt;windowheight){y_cord=windowheight;} layoutParams1.leftMargin = x_cord -25; layoutParams1.topMargin = y_cord - 75; ball1.setLayoutParams(layoutParams1); break; default : break; } } return true;} } </code></pre> <pre><code> &lt;!-- main.xml --&gt; &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;ImageView android:layout_width="50sp" android:layout_height="50sp" android:id="@+id/ball" android:src="@drawable/ball"&gt; &lt;/ImageView&gt; &lt;ImageView android:layout_y="30dip" android:layout_x="118dip" android:layout_width="50sp" android:layout_height="50sp" android:id="@+id/ball1" android:src="@drawable/ball1"&gt; &lt;/ImageView&gt; &lt;/LinearLayout&gt; </code></pre> <p>Anyone plz help me out..Trying all possible thing to solve it..</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
