Question

我有一个游戏，我需要让苹果掉下来，但我有一个问题。（动画相同）当我点击按钮1苹果掉落，但是当我再次点击按钮时，1个苹果擦除，然后再次掉落。当我点击按钮时我怎么能做到这一点我已经掉了aple，当再次点击时，第一个苹果不能擦除。现在我有了这段代码

public void limonplus(View v){
        final ImageView floatingImage = (ImageView)findViewById(R.id.imageView1);
        Random random = new Random();   
        TranslateAnimation  anim = new TranslateAnimation(
        Animation.RELATIVE_TO_PARENT, random.nextFloat(),
        Animation.RELATIVE_TO_PARENT, random.nextFloat(),
        Animation.RELATIVE_TO_PARENT, 0f,
        Animation.RELATIVE_TO_PARENT, 1f);          
        anim.setDuration(1800);
        floatingImage.startAnimation(anim);           
    }

工作原理：首先，创建ImageView的新实例。然后开始动画并完成动画 - 从父版面中删除图像。以下是Activity的代码：

public class MyActivity extends Activity implements View.OnClickListener {

Button button;
FrameLayout fl;
ImageView view;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    button = (Button)findViewById(R.id.button_drop);
    button.setOnClickListener(this);
}

public void limonplus(){
    view = new ImageView(getApplicationContext());
    view.setImageResource(R.drawable.image_resource);
    view.setLayoutParams(new ViewGroup.LayoutParams(
            ViewGroup.LayoutParams.WRAP_CONTENT,
            ViewGroup.LayoutParams.WRAP_CONTENT));
    fl = (FrameLayout)findViewById(R.id.frameLayout1);
    fl.addView(view);
    Random random = new Random();
    TranslateAnimation anim = new TranslateAnimation(
            Animation.RELATIVE_TO_PARENT, random.nextFloat(),
            Animation.RELATIVE_TO_PARENT, random.nextFloat(),
            Animation.RELATIVE_TO_PARENT, 0f,
            Animation.RELATIVE_TO_PARENT, 1f);
    anim.setDuration(1800);
    anim.setAnimationListener(new Animation.AnimationListener() {
        public void onAnimationStart(Animation paramAnimation) { }
        public void onAnimationRepeat(Animation paramAnimation) { }
        public void onAnimationEnd(Animation paramAnimation) {
            fl.post(new Runnable() {
                public void run() {
                    runOnUiThread(new Runnable() {
                        public void run() {
                            fl.removeAllViews();
                        }
                    });
                }
            });
        }
    });
    view.startAnimation(anim);
}

@Override
public void onClick(View view) {
    Log.d("myLog","Dropped");
    limonplus();
}
}

以下是main.xml的代码：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:id="@+id/parent"
android:layout_height="match_parent">
<Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Drop"
        android:id="@+id/button_drop" android:layout_gravity="left|top" android:layout_alignParentLeft="true"
        android:layout_marginLeft="0dp" android:layout_alignParentTop="true" android:layout_marginTop="0dp"/>
<FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" android:id="@+id/frameLayout1">
</FrameLayout>
</RelativeLayout>

希望，它解决了你的问题：）

我需要一次启动1-100个动画
