Android6.0申请弹出悬浮窗权限

使用Action Settings.ACTION_MANAGE_OVERLAY_PERMISSION 启动隐式Intent 使用 “package:” + getPackageName() 携带App的包名信息 使用 Settings.canDrawOverlays 方法判断授权结果

private static final int REQUEST_CODE = 1;

private void requestAlertWindowPermission() {
    Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
    intent.setData(Uri.parse("package:" + getPackageName()));
    startActivityForResult(intent, REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE) {
        if (Settings.canDrawOverlays(this)) {
            Log.i(LOGTAG, "onActivityResult granted");
        }
    }
}
