嗨，我正在制作一个用于控制需要（WRITE_SETTINGS）权限的设备屏幕的应用程序，我使用了一种方法来请求权限，但应用程序崩溃了。我的应用程序检查版本是否高于 android 5 或更高版本它调用方法来请求权限但它不会工作，有什么帮助吗？

public class MainActivity extends AppCompatActivity {

      SeekBar sb;
      TextView prog;
      Context context;
      int Brightness;
      boolean pergranted;



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

          int MyVersion = Build.VERSION.SDK_INT;
          if (MyVersion > Build.VERSION_CODES.LOLLIPOP_MR1) {
              if (!checkIfpermissiongranted()) {
                  requestPermission();

              }


              sb = (SeekBar) findViewById(R.id.seekBar);
              prog = (TextView) findViewById(R.id.Progress);
              context = getApplicationContext();


              //Getting current screen brightness
              Brightness = Settings.System.getInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS, 0);

              //Setting current screen brightness to seekbar
              sb.setProgress(Brightness);

              //Setting current screen brightness to textview
              prog.setText(R.string.current_brightness + Brightness);





              sb.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {@
                  Override
                  public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
                      if (pergranted) {
                          prog.setText(R.string.current_brightness + progress);
                          //Changing brightness on seekbar change
                          Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS, progress);
                      }
                  }@
                  Override
                  public void onStartTrackingTouch(SeekBar seekBar) {

                  }

                  @
                  Override
                  public void onStopTrackingTouch(SeekBar seekBar) {

                  }
              });
          }


      }

      private boolean checkIfpermissiongranted() {
          int result = ContextCompat.checkSelfPermission(this, Manifest.permission.GET_ACCOUNTS);
          if (result == PackageManager.PERMISSION_GRANTED) {
              return true;
          } else {
              return false;
          }
      }



      private void requestPermission() {
          ActivityCompat.requestPermissions(this, new String[] {
              Manifest.permission.WRITE_SETTINGS
          }, 1);
      }

      @
      Override
      public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
          switch (requestCode) {
              case 1:
                  if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                      pergranted = true;

                  }
          }


      }

  }

用这个

prog.setText(getReso‌​urces().getString(R.s‌​tring.current_brightn‌​ess)+" " + String.valueOf(Brigh‌​tness));

检查带有字符串资源 ID #0x7f060073 的 R.java 文件。可能它不存在。添加后清理并重建项目。崩溃不是由于运行时异常

错误在 MainActivity 的第 58 行，这是一个简单的错误，包含您的代码以使用String.valueof()方法，这将纠正 Resources$NotFoundE‌​xception

改变

prog.setText(R.string.current_brightness + progress);

至

prog.setText(getResources().getString(R.string.current_brightness) + progress);

并检查current_brightness字符串资源的拼写和可用性。

在您的onRequestPermissionsResult添加案例 0，因为当用户允许权限时requestCode 将为 0。

 @ Override
          public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
              switch (requestCode) {
                  case 0:
                      if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                          pergranted = true;

                      }
              }

问题出现在行 prog.setText(R.string.current_brightness + progress); 和prog.setText(R.string.current_brightness + Brightness);

( docs ) 方法与字符串资源 id 一起使用，例如您在示例中使用setText(int)的. 此资源 id 是一个整数，表示字符串在生成的文件中的位置。R.string.current_brightness

通过尝试将字符串连接在一起，您实际上已经完成了整数加法，并且该setText(int)方法正在以字符串的 id和当前进度查找资源。

您需要在这里使用的是格式化字符串，如下所示：

<string name="current_brightness">Current: %1$d</string>

然后通过以下方式使用setText(CharSequence, Object... formatArgs)（docs ）解析字符串并对其进行格式化：

prog.setText(getString(R.string.current_brightness, progress));

或者，您根本不必修改字符串，并且可以使用以下内容：

prog.setText(getString(R.string.current_brightness) + progress);

如果getString()找不到，将其替换为getResources().getString()
