我啓動一個線程通過TextureView到getBitmap，但是，我得到一個異常：TextureView getBitmap java.lang.IllegalStateException
E/AndroidRuntime: FATAL EXCEPTION: Thread-814
java.lang.IllegalStateException: Hardware acceleration can only be used with a single UI thread.

在我的代碼
private TextureView demo2VideoTtv;
public Bitmap getFrame() {
//這裏會造成抖動
long start = System.currentTimeMillis();
demo2VideoTtv.getBitmap(mFrame); // here throw exception
Log.d("SecondActivity", "getFrame time" + (System.currentTimeMillis() - start));
//裁剪圖片
mFrame_part = Bitmap.createBitmap(mFrame, demo2ColorfulText.getLeft(), demo2ColorfulText.getTop(), demo2ColorfulText.getWidth(), demo2ColorfulText.getHeight());
return mFrame_part;
}
