Question

标题基本上说明了这个问题。我提到了这个问题：https://english.stackexchange.com/questions/11481解决了后一个问题，但后来却给了我前一个问题。

public class PbfSampleApplication extends Application {
public static final String TAG = "PbfSampleApplication";

@Override
public void onCreate() {
    super.onCreate();


    startService(new Intent(this.getApplicationContext(), 
PbfSampleService.class));

    FlicManager.init(this.getApplicationContext(), "2125f7c3-0d0e-42d5-88fe-
fda8765867d6", "94d6448c-22d3-4d2e-951f-f625f60f471a");

    FlicManager manager = FlicManager.getManager();

    for (FlicButton button : manager.getKnownButtons()) {
        button.connect();
        listenToButtonWithToast(button);
    }
}


public void listenToButtonWithToast(FlicButton button) {
    button.addEventListener(new FlicButtonAdapter() {
        @Override
        public void onButtonUpOrDown(FlicButton button, boolean wasQueued, int timeDiff, boolean isUp, boolean isDown) {
            if (isDown) {


                View v =LayoutInflater.inflate(R.layout.activity_main);
                 //Above line has the error
                View innerView = v.findViewById(R.id.number);           

                Toast.makeText(getApplicationContext(), "Button " + button + " was pressed", Toast.LENGTH_SHORT).show();
                Intent callIntent = new Intent(Intent.ACTION_CALL);
                callIntent.setData(Uri.parse("tel:017702329065"));
                startActivity(callIntent);


            }
        }
    });
}
}

我知道我应该传入一个int但是当我在开发者网站上检查方法时，看起来参数格式正确，所以我不知道还需要我还需要什么工作

Answer 1

在调用之前创建一个LayoutInflater实例：

<span>text</span>

第二个参数是LayoutInflater inflater = LayoutInflater.from(getContext()); View v = inflater.inflate(R.layout.activity_main, null); View innerView = v.findViewById(R.id.number);，可以为null。 ViewGroup没有只带一个参数的inflate方法

找不到适合inflate（int）的方法，尝试在活动之外使用findViewbyID
