android - 在 Android 中切换飞行模式

Question

我做错了吗？它不起作用。

public void airplane() {
    boolean isEnabled = Settings.System.getInt(this.getApplicationContext().getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0) == 1;
    Settings.System.putInt(context.getContentResolver(),Settings.System.AIRPLANE_MODE_ON,isEnabled ? 0 : 1);
    //Settings.System.putInt(this.getApplicationContext().getContentResolver(),Settings.System.AIRPLANE_MODE_ON,isEnabled ? 0 : 1);
    Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
}

Answer 1

This answer包含执行此操作所需的代码。还要确保您拥有 WRITE_SETTINGS 权限。

改编自Controlling Airplane Mode :

// read the airplane mode setting
boolean isEnabled = Settings.System.getInt(
      getContentResolver(), 
      Settings.System.AIRPLANE_MODE_ON, 0) == 1;

// toggle airplane mode
Settings.System.putInt(
      getContentResolver(),
      Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1);

// Post an intent to reload
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !isEnabled);
sendBroadcast(intent);
