Question

在我的活动中，我有以下代码：

int picture = Const.a1;
Const.backgroundBitmap = BitmapFactory.decodeResource(getResources(), picture);
Const.backgroundBitmapBonus0 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[0]);
Const.backgroundBitmapBonus1 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[1]);
Const.backgroundBitmapBonus2 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[2]);
Const.backgroundBitmapBonus3 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[3]);

Const.bitmapBackBonus = new Bitmap[4];

Const.bitmapBackBonus[0]= Const.backgroundBitmapBonus0;
Const.bitmapBackBonus[1] = Const.backgroundBitmapBonus1;
Const.bitmapBackBonus[2] = Const.backgroundBitmapBonus2;
Const.bitmapBackBonus[3] = Const.backgroundBitmapBonus3;

在Const班级我有

public static int[] bonus_back = {  R.drawable.back_b0 ,    R.drawable.back_b1 ,    R.drawable.back_b2 ,    R.drawable.back_b3};

当我在我的设备上运行应用程序时，它会崩溃，而在AVD中则可以正常运行。

如何以正确的方式使用这些图片？

修改

使用http://developer.android.com/training/displaying-bitmaps/load-bitmap.html的新代码仍然是同样的问题

    Const.screenWidth = this.getWindowManager().getDefaultDisplay().getWidth();
    Const.screenHeight = this.getWindowManager().getDefaultDisplay().getHeight();

    int picture = Const.a1; 
    Const.backgroundBitmapBonus0 = decodeSampledBitmapFromResource(getResources(), Const.bonus_back[0], Const.screenWidth, Const.screenHeight);
    Const.backgroundBitmapBonus1 =decodeSampledBitmapFromResource(getResources(), Const.bonus_back[1], Const.screenWidth, Const.screenHeight);
    Const.backgroundBitmapBonus2 = decodeSampledBitmapFromResource(getResources(), Const.bonus_back[2], Const.screenWidth, Const.screenHeight);
    Const.backgroundBitmapBonus3 = decodeSampledBitmapFromResource(getResources(), Const.bonus_back[3], Const.screenWidth, Const.screenHeight);

    Const.backgroundBitmap = decodeSampledBitmapFromResource(getResources(), picture, 100, 100);


    /*Const.backgroundBitmap = BitmapFactory.decodeResource(getResources(), picture);
    Const.backgroundBitmapBonus0 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[0]);
    Const.backgroundBitmapBonus1 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[1]);
    Const.backgroundBitmapBonus2 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[2]);
    Const.backgroundBitmapBonus3 = BitmapFactory.decodeResource(getResources(), Const.bonus_back[3]);
     */
    Const.bitmapBackBonus = new Bitmap[4];

    Const.bitmapBackBonus[0]= Const.backgroundBitmapBonus0;
    Const.bitmapBackBonus[1] = Const.backgroundBitmapBonus1;
    Const.bitmapBackBonus[2] = Const.backgroundBitmapBonus2;
    Const.bitmapBackBonus[3] = Const.backgroundBitmapBonus3;

Answer 1

如果图像太大，则可能是内存不足。

检查http://developer.android.com/training/displaying-bitmaps/load-bitmap.html以了解如何加载图片的缩小版本。

应用程序因大局而崩溃
