Android 整个手机屏幕截图和去除状态栏截图

一、去除状态栏截图

  //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);

二、整个手机屏幕截图，但状态栏是空白

View view = getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap bitmap = view.getDrawingCache();

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