我有两个动画 xml 文件,我在 java 类中使用它们。我希望我的动画重复 1000 毫秒。我写了这段代码,但是当我运行这个程序时,动画不会重复。我在 repeatAnim() 函数中使用 Timer,但我认为这在 1000 毫秒内不起作用。
相对的.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:id="@+id/txt1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/txt1"
></TextView>
<ImageButton
android:id="@+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/pic1"
android:layout_gravity="center"/>
</LinearLayout>
开关类.java:
public class SwitchClass extends Activity implements AnimationListener{
Animation animation1;
Animation animation2;
boolean frontButton=true;
ImageButton btn;
Timer timer;
TimerTask mTimerTask;
Handler handler=new Handler();
boolean repeat=true;
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.relative);
animation1=AnimationUtils.loadAnimation(this, R.anim.to_middle);
animation1.setAnimationListener(this);
animation2=AnimationUtils.loadAnimation(this, R.anim.from_middle);
animation2.setAnimationListener(this);
btn=(ImageButton)findViewById(R.id.btn2);
btn.setOnClickListener(onClickListener);
repeatAnimation();
repeatAnim();
}
private OnClickListener onClickListener=new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent=new Intent(SwitchClass.this,AnimClass.class);
startActivity(intent);
}
};
@Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
if(animation==animation1){
if(frontButton){
btn.setImageResource(R.drawable.pic2);
}
else{
btn.setImageResource(R.drawable.pic1);
}
btn.clearAnimation();
btn.setAnimation(animation2);
btn.startAnimation(animation2);
}
else{
frontButton=!frontButton;
btn.setEnabled(true);
}
}
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
public void repeatAnim(){
timer=new Timer();
mTimerTask=new TimerTask(){
public void run(){
handler.post(new Runnable(){
public void run(){
repeatAnimation();
}
});
}
};
timer.schedule(mTimerTask, 1000);
}
public void repeatAnimation(){
btn.setEnabled(false);
btn.clearAnimation();
btn.setAnimation(animation1);
btn.startAnimation(animation1);
}
}
感谢您的建议。干杯
