我正在開發一個android遊戲。它幾乎已經完成並在10.1平板電腦，nexus 7，nexus 4，HTC senstation上嘗試過，它可以在所有這些平臺上運行。然而，當我在Galaxy s3上試用它時，我在幀動畫xml中調用圖片時出現了OutofMemory錯誤。現在我通過調整xhdpi文件夾中的圖片來解決這個問題，但結果並不令人滿意。有沒有足夠的方法可以用來重新縮放在動畫中顯示的圖片以進行幀動畫。OutOfMemory錯誤android
下面是代碼：
public class Logo extends Activity {
private ImageView iv;
Thread timer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_logo);
iv = (ImageView) findViewById(R.id.imageView1);
iv.setBackgroundResource(R.anim.anime);
// thread for animating the logo and moving to next activity after
// display.
timer = new Thread() {
@Override
public void run() {
try {
sleep(7000);
} catch (InterruptedException e) {
e.printStackTrace();
} finally {
//Intent i = new Intent();
//i.setClass(Logo.this, StartPoint.class);
//startActivity(i);
}
}
};
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
super.onWindowFocusChanged(hasFocus);
AnimationDrawable anime = (AnimationDrawable) iv.getBackground();
if (hasFocus) {
anime.start();
timer.start();
} else {
anime.stop();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.logo, menu);
return true;
}
@Override
protected void onStop() {
// TODO Auto-generated method stub
super.onStop();
finish(); // to remove this activity.
}
}
這裏是anime.xml：
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android
android:oneshot="true">
<item android:drawable="@drawable/a1" android:duration="60" />

</animation-list>
現在我看到了很多答案，說明bitmapFactory.options 但我怎麼能應用在XML這些選項文件，如果它不可能。有沒有其他方法可以使用，而不是調整圖片的大小。 預先感謝您。
這裏我試圖programmaticaly應用的代碼，仍然得到了同樣的錯誤：
//onCreate and thread then
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
super.onWindowFocusChanged(hasFocus);

您是否試圖以編程方式創建動畫？ – sandrstar
不，我不認爲這是可能的，即時通訊將閱讀有關它，所以你說如果我以編程方式實現它，我可以在圖片上添加bitmapfactory的選項？ – Coderji
以及事情是你永遠不知道哪個設備可以支持這個以及哪個設備cannot ..檢查DDMS視圖中的堆內存你有設備..還有sandrstar建議你可以動畫編程..它會解決問題經常 – user632905
