我需要捕捉当前屏幕的屏幕截图,所以我在
上采用了以下代码protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
LinearLayout v = (LinearLayout) findViewById(R.id.mainLayout);
v.setDrawingCacheEnabled(true);
// this is the important code :)
// Without it the view will have a
// dimension of 0,0 and the bitmap will
// be null
v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
//v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
v.layout(0, 0, v.getWidth(), v.getHeight());
v.buildDrawingCache(true);
Bitmap bm = Bitmap.createBitmap(v.getDrawingCache());
v.setDrawingCacheEnabled(false); //
if (bm != null) {
try {
String path = Environment.getExternalStorageDirectory()
.toString();
OutputStream fOut = null;
File file = new File(path, "screentest.jpg");
fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
Log.e("ImagePath", "Image Path : "
+ MediaStore.Images.Media.insertImage(
getContentResolver(), file.getAbsolutePath(),
file.getName(), file.getName()));
} catch (Exception e) {
e.printStackTrace();
}
}
}
此代码对我来说很好,但我需要在屏幕加载完成后捕获屏幕。
我也尝试过onPostCReate(),但一切都是徒劳的..
我也尝试在onPause()方法中调用代码,但是由于动画,屏幕从右边和底部开始略微调整......所以我甚至不能去寻找...
现在轮到你分享你的专业知识了。
非常感谢任何建议!!!!

试试这个:
public void onCreate(Bundle savedInstanceState) { LinearLayout v = (LinearLayout) findViewById(R.id.mainLayout); v.setDrawingCacheEnabled(true); v.post(new Runnable() { public void run() { // Code to take screenshot }); } }
