Question

我在这里找到了很多例子，但没有人能为我工作......我无法理解什么是错的。我需要的是在我的应用程序中输入“飞行模式”并搜索完整的例如，
我所做的是
1.请求舱单中的许可（我看过我需要“WRITE_SETTINGS”许可）

<uses-permission-sdk-m android:name="android.permission.WRITE_SETTINGS" />

2.在代码中，当我想改变飞行模式时，我会检查是否允许

private void setAirplaneMode() {
    boolean permission;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        permission = Settings.System.canWrite(this);
    } else {
        permission = ContextCompat.checkSelfPermission(this, android.Manifest.permission.WRITE_SETTINGS) == PackageManager.PERMISSION_GRANTED;
    }

    if (permission) {
        //here I go to activate the airplane mode
        setAirplaneModeIntent(true);
    } else {
        if (ActivityCompat.shouldShowRequestPermissionRationale(this, android.Manifest.permission.WRITE_SETTINGS)) {
            //I need to explain why I want permission
            //TODO
        } else {
            ActivityCompat.requestPermissions(this, new String[] android.Manifest.permission.WRITE_SETTINGS}, MY_PERMISSION_REQUEST_WRITE_SETTINGS);
        }
    }

3.我覆盖了“onRequestPermissionsResult”

public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResult) {

    switch (requestCode) {
        case MY_PERMISSION_REQUEST_WRITE_SETTINGS: {
            if( grantResult.length > 0 &&
                grantResult[0] == PackageManager.PERMISSION_GRANTED) {
                setAirplaneModeIntent(true);
            }
        }
    }
}

4.在“setAirplaneModeIntent”中我设置了飞行模式

private void setAirplaneModeIntent(boolean activateAirplaneMode) {
    Settings.System.putInt(getContentResolver(), Settings.System.AIRPLANE_MODE_ON,
            activateAirplaneMode ? 1 : 0);        

    Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
    intent.putExtra("state", activateAirplaneMode);
    sendBroadcast(intent);
}

当我调试时，我输入“ActivityCompat.requestPermissions”代码但当我到达“onRequestPermissionsResult”时，结果不是PackageManager.PERMISSION_GRANTED。
怎么了？

的修改
我解决了“requestPermissions”部分。对于“WRITE_SETTINGS”权限，您需要ACTION_MANAGE_WRITE_SETTINGS意图见这里：

无论如何，当我发送广播时，我在第4点遇到了错误如果我没有发送广播，“Settings.System.putInt”命令似乎什么都不做有人可以帮帮我吗？

编辑2
我投降。我发现唯一可行的方法是以这种方式打开网络设置

Intent intentAirplaneMode = new Intent(Settings.ACTION_AIRPLANE_MODE_SETTINGS);
intentAirplaneMode.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intentAirplaneMode);
