所以我正在创建一个应用程序，当你第一次打开它时，你可以选择使用WiFi或数据来检索oAuth2的数据（仍然需要弄明白）。但是，我的导航抽屉中还有一个设置按钮，其中包含一个启用或禁用使用数据的无线电组。如果该人说要启用数据，我关闭他们的WiFi（我不应该这样做）我应该检查连接状态，每当连接等于移动数据然后开始上传，如果他们点击禁用检查连接是什么时候WiFi并开始上传。但是，我现在不知道该怎么做，除非现在比我聪明的人能让我知道，就是这样。
但是，我在保存按钮状态时按下了保存按钮，然后在打开应用程序时加载该状态/决定。此外，默认情况下它被设置为禁用，但是，如果用户在应用程序启动弹出窗口中单击“使用单元格”，我想更改该值。
我真的更喜欢学习如何做这些东西的帮助，所以非常感谢任何帮助。
这是我的MainActivity.java

以下是控制应用启动对话框的代码。
public class WifivsDataDialog extends DialogFragment implements View.OnClickListener {
private CheckBox checkBox;
private Button button1;
private Button button2;
@Override

super.onCreate(savedInstanceState);

button1.setOnClickListener(this);
button2.setOnClickListener(this);
checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
// Store the isChecked to Preference here

SharedPreferences.Editor editor = sharedPref.edit();
editor.putBoolean("DONT_SHOW_DIALOG", isChecked);
editor.commit();
}
});
return mainView;
}
@Override
public void onClick(View view) {
switch (view.getId()) {
