setDrawingCacheEnabled

Question

finalImgscreen //My View. 

finalImage  //My Bitmap 

finalImgscreen.setDrawingCacheEnabled(true); 

finalImage = finalImgscreen.getDrawingCache(); 

這對於QVGA屏幕模擬器/設備很好，但在HVGA屏幕模擬器/設備上顯示黑屏。

你能幫我解決嗎。

Answer 1

調用getDrawingCache()

呼叫onLayout(boolean changed, int left, int top, int right, int bottom);

之前嘗試onLayout(true,0,0,100,100);
