Android6.0权限的问题

dream_zfr 2017-03-15 11:44:36

我在测试Android6.0权限的问题的时候使用华为的手机测试的时候不会申请权限的时候不会弹出系统自带的Dialog提示用户进行相关的权限操作而是直接自己去申请了对应的权限这个是怎么回事啊

public class MainActivity extends AppCompatActivity implements View.OnClickListener {



    private Button btnRequestCamera;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        initView();

    }



    private void initView() {

        btnRequestCamera = (Button) findViewById(R.id.btn_request_camera);

        btnRequestCamera.setOnClickListener(this);

    }



    @Override

    public void onClick(View v) {

        switch (v.getId()) {

            case R.id.btn_request_camera:

                checkPer();

                break;

        }

    }



    private void checkPer() {

        int permission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR);

        if (permission == PackageManager.PERMISSION_GRANTED) {

            Toast.makeText(this, "权限申请成功", Toast.LENGTH_SHORT).show();

        } else {

            Toast.makeText(this, "权限没有申请", Toast.LENGTH_SHORT).show();

            new AlertDialog.Builder(this)

                    .setTitle("请求日历权限")

                    .setMessage("程序申请日历权限读取日历的相关内容")

                    .setPositiveButton("同意开启", new DialogInterface.OnClickListener() {

                        @Override

                        public void onClick(DialogInterface dialog, int which) {

                            ActivityCompat.requestPermissions(MainActivity.this,

                                    new String[]{Manifest.permission.READ_CALENDAR, Manifest.permission.WRITE_CALENDAR}, 100);

                        }

                    }).setNegativeButton("取消开启", new DialogInterface.OnClickListener() {

                @Override

                public void onClick(DialogInterface dialog, int which) {

                    finish();

                }

            }).setCancelable(false).show();



        }

    }



    @Override

    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

        switch (requestCode) {

            case 100:

                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {

                    Toast.makeText(this, "日历权限申请成功", Toast.LENGTH_SHORT).show();

                }else

                    Toast.makeText(this, "日历权限申请失败", Toast.LENGTH_SHORT).show();

                break;

        }

        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    }

}
