//整个手机屏幕的视图
View view = getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();

Bitmap bitmap = view.getDrawingCache();

// 获取状态栏高度
Rect frame = new Rect();
getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
int statusBarHeight = frame.top;
Log.i("TAG", "" + statusBarHeight);

// 获取屏幕长和高
int width = getWindowManager().getDefaultDisplay().getWidth();
int height = getWindowManager().getDefaultDisplay().getHeight();

Bitmap b = Bitmap.createBitmap(bitmap, 0, statusBarHeight, width, height - statusBarHeight);

//保存图片
FileOutputStream fout = null;
try {
fout = new FileOutputStream(Environment.getExternalStorageDirectory().getAbsolutePath() + "/test.png");
} catch (FileNotFoundException e) {
e.printStackTrace();
}
b.compress(Bitmap.CompressFormat.PNG, 100, fout);
//显示截图
mImageView.setImageBitmap(b);
