使用：在相应的Activity继承MPermissionsActivity

public class MainActivity extends MPermissionsActivity 

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    

    /**
     * 打电话
     *
     * @param view
     */
    public void onClick1(View view) 
        requestPermission(new String[]Manifest.permission.CALL_PHONE, 0x0001);
    

    /**
     * 写SD卡
     *
     * @param view
     */
    public void onClick2(View view) 
        requestPermission(new String[]Manifest.permission.WRITE_EXTERNAL_STORAGE, 0x0002);
    

    /**
     * 拍照
     *
     * @param view
     */
    public void onClick3(View view) 
        requestPermission(new String[]Manifest.permission.CAMERA, 0x0003);
    

    /**
     * 权限成功回调函数
     *
     * @param requestCode
     */
    @Override
    public void successPermission(int requestCode) 
        super.successPermission(requestCode);
        switch (requestCode) 
            case 0x0001:
                Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:[phone]"));
                if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) 
                    // TODO: Consider calling
                    //    ActivityCompat#requestPermissions
                    // here to request the missing permissions, and then overriding
                    //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
                    //                                          int[] grantResults)
                    // to handle the case where the user grants the permission. See the documentation
                    // for ActivityCompat#requestPermissions for more details.
                    return;
                
                startActivity(intent);
                break;
