您好，我正在制作一个用于控制设备屏幕的应用程序，该应用程序需要(WRITE_SETTINGS)权限，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 或不高于它调用一个方法来请求权限，但它不起作用，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;
}
}
}
}

最佳答案
错误位于 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
