I am trying to convert a linear layout using animation, left & # 8596; right like that. but i got some error

Question

This is my first application, I am trying to translate from right to left or left to right.

Here is the code

Res> anim> translate_left

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" Android: interpolator="@Android: anim/accelerate_decelerate_interpolator" > <translate android:fromXDelta="100%p" android:toXDelta="0%p" android:duration="500" android:repeatCount="0" android:fillAfter="true" /> </LinearLayout> 

Res> anim> translate_right

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:interpolator="@android:anim/accelerate_decelerate_interpolator" > <translate android:fromXDelta="0%p" android:toXDelta="100%p" android:duration="500" android:repeatCount="0" android:fillAfter="false" /> </LinearLayout> 

and

 import android.app.Activity; import android.os.Bundle; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.view.animation.Animation; import android.view.animation.Animation.AnimationListener; import android.view.animation.AnimationUtils; import android.widget.Button; import android.widget.LinearLayout; public class MatchingActivity extends Activity { boolean isPageOpen = false; Animation translateLeftAnim; Animation translateRightAnim; LinearLayout slidingPage01; Button openBtn01; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.matching); // Sliding Page slidingPage01 = (LinearLayout)findViewById(R.id.slidingPage01); translateLeftAnim = AnimationUtils.loadAnimation(this, R.anim.translate_left); translateRightAnim = AnimationUtils.loadAnimation(this, R.anim.translate_right); SlidingPageAnimationListener animListener = new SlidingPageAnimationListener(); translateLeftAnim.setAnimationListener(animListener); translateRightAnim.setAnimationListener(animListener); // Open Button openBtn01 = (Button) findViewById(R.id.openBtn01); openBtn01.setOnClickListener(new OnClickListener() { public void onClick(View v) { // start animation if (isPageOpen) { slidingPage01.startAnimation(translateRightAnim); } else { slidingPage01.setVisibility(View.VISIBLE); slidingPage01.startAnimation(translateLeftAnim); } } }); } private class SlidingPageAnimationListener implements AnimationListener { public void onAnimationEnd(Animation animation){ if (isPageOpen) { slidingPage01.setVisibility(View.INVISIBLE); openBtn01.setText("Open"); isPageOpen = false; } else { openBtn01.setText("Close"); isPageOpen = true; } } public void onAnimationRepeat(Animation animation){} public void onAnimationStart(Animation animation){} } } 

After running this code, some error appears!

I am also stuck in a similar situation in which I need to lay out the layout in all directions, but I did it below, my code can help you.

 Animation Left slide <translate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="500" android:fromXDelta="100%" android:toXDelta="0%" > </translate> Animation Right slide <translate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="500" android:fromXDelta="-100%" android:toXDelta="0%" > </translate> RightSwipe = AnimationUtils.loadAnimation(Screen.this, R.anim.right_swipe); ScreenAnimation.startAnimation(RightSwipe);
