Android中添加授权操作

Android 6.0之后，需要用户进行授权
不仅需要在配置文件中添加授权
   

<uses-permission android:name="android.permission.CALL_PHONE" />

还需要在请求的地方添加：

    if(ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CALL_PHONE)
            != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(MainActivity.this, new String[]{Manifest.permission.CALL_PHONE}, 1);
    } else {
        call();
    }

 

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case 1:
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    call();
                } else {
                    Toast.makeText(this, "You denied the permission", Toast.LENGTH_SHORT).show();
                }
                break;
            default:
        }
    }
