【问题描述】：

嗨，我正在制作一个需要（WRITE_SETTINGS）权限的设备屏幕控制应用程序，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 或不更高它调用一个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() {@

                          //Changing brightness on seekbar change
                          Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS, progress);

                  }
              });
          }


      }

      private boolean checkIfpermissiongranted() {

          } else {
              return false;
          }

              Manifest.permission.WRITE_SETTINGS
          }, 1);
      }

      Override

【问题讨论】：

你能提供LOGCAT的日志吗？
我会添加logcat
检查这一行Caused by: android.content.res.Resources$NotFoundException: String resource ID
Resources$NotFoundException: String resource ID #0x7f060073 检查R.id.Progress 文本视图
我检查了它已经存在（文本视图）

标签： java android android-permissions runtime-permissions

【解决方案1】：

使用这个

prog.setText(getReso‌urces().getString(R.s‌tring.current_brightn‌ess)+" " + String.valueOf(Brigh‌tness));

【讨论】：

尝试解释你的代码为什么以及做什么来解决出现的问题。一个好的答案不仅仅是一行代码。

【解决方案2】：

在您的 onRequestPermissionsResult 中添加案例 0，因为当用户将允许权限 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;

                      }
              }

【讨论】：

【解决方案3】：

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

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

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，setText(int) 方法正在以字符串的 id 查找资源加上当前进度。

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>

然后使用setText(CharSequence, Object... formatArgs) (docs) 以下列方式解析字符串并对其进行格式化：

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

或者，您根本不必修改您的字符串，并且可以使用以下内容：

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

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

【讨论】：

【解决方案4】：

改变

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

到

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。

【讨论】：

【解决方案5】：

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

【讨论】：

prog.setText(getResources().getString(R.string.current_brightness)+" " + String.valueOf(Brightness));

【解决方案6】：

使用字符串资源 ID #0x7f060073 检查您的 R.java 文件。可能它不存在。添加后清理并重建项目。崩溃不是因为运行时异常
