Little assistance with translate animation

Hey! Basically, I have this little animation of this text that \"slides\" down when a person clicks the screen.

Hey! Basically, I have this little animation of this text that "slides" down when a person clicks the screen.

It takes 6 seconds to slide from top to the bottom.

While it is sliding if someone clicks the screen again, I want to replace that animation with another animation which makes it go left/right or anything different. Basically, replace the translate.xml animation with some_other_animation.xml right from that spot (not from the beginning).

(My eventual idea is to make it "explode"). Any help appreciated.

My files: Main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/root"
 android:layout_width="fill_parent" android:layout_height="fill_parent"
 xmlns:android="http://schemas.android.com/apk/res/android"     android:gravity="top|center">
    <TextView android:id="@+id/animatedText" android:layout_height="wrap_content"     android:text="@string/hello" android:layout_width="wrap_content"></TextView>
</LinearLayout>

Strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <string name="hello">Just a sample string!</string>
 <string name="app_name">Ryan Sample</string>

</resources>

Animation class:

package com.ryan.test.animsxx;

import java.util.Timer;
import java.util.TimerTask;

import android.app.Activity;
import android.os.Bundle;
imp开发者_C百科ort android.os.Handler;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.LinearLayout;
import android.widget.TextView;

public class AnimationActivity extends Activity {
 /** Called when the activity is first created. */
 @Override public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
 final Animation a = AnimationUtils.loadAnimation(this, R.anim.translate);
 a.reset();
 final TextView rText = (TextView) findViewById(R.id.animatedText);

 LinearLayout layout = (LinearLayout) findViewById(R.id.root);
 layout.setOnClickListener(new OnClickListener() {
 @Override public void onClick(View v) {
 rText.startAnimation(a);

 }
 });

 }
}

Translate.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
 android:fromXDelta="0%" android:toXDelta="0%" android:fromYDelta="0%"
 android:toYDelta="300%" android:duration="6000" android:zAdjustment="bottom" />

Manifest:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.ryan.test.animsxx"
  android:versionCode="1"
  android:versionName="1.0">
<uses-sdk android:minSdkVersion="8" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".AnimationActivity"
 android:label="@string/app_name">
 <intent-filter>
 <action android:name="android.intent.action.MAIN" />
 <category android:name="android.intent.category.LAUNCHER" />
 </intent-filter>
 </activity>

</application>
</manifest>


Um, your "second" animation cannot be defined with xml, since it depends on a runtime event. You could construct a new animation in code, based on the location of the touch event.
