这是我的第一个应用程序，我尝试将翻译从右向左或从左向右。
这是代码
Res＆gt;动画＆gt; 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＆gt;动画＆gt; 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>
和

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){}
}
}
启动此代码后会出现一些错误！
错误是

我也陷入了类似的情况，我必须向所有方向滑动布局，但我在下面完成的是我的代码可能对你有帮助。
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);
