返回类型与AdapterView.OnItemLongClickListener.onItemLongClick(AdapterView<?>，视图、int、long不兼容)

Question

在我的小部件中，当列表视图中的项被长按时，我希望启动该项目(然而，在我目前的编码中，普通的单击也会这样做，但现在我正在做一些长点击，以便在以后需要更改长单击所做的操作时设置它)。

这是我的编码：

package com.example.awesomefilebuilderwidget;

import android.app.Activity;
import android.content.pm.ApplicationInfo;
import android.os.Bundle;
import android.text.Editable;
import android.text.TextWatcher;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemLongClickListener;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.AdapterView.OnItemClickListener;

public class Drag_and_Drop_App extends Activity {
private ListView mListAppInfo;
// Search EditText
EditText inputSearch;


@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // set layout for the main screen
    setContentView(R.layout.drag_and_drop_app);
    // create new adapter
    AppInfoAdapter adapter = new AppInfoAdapter(this, Utilities.getInstalledApplication(this), getPackageManager());
    // set adapter to list view
    mListAppInfo.setAdapter(adapter);
    // search bar
    inputSearch = (EditText) findViewById(R.id.inputSearch);

    inputSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
            // When user changed the Text
            Drag_and_Drop_App.this.adapter.getFilter().filter(cs);  

        }

        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                int arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub                          
        }
        });
     // load list application
    mListAppInfo = (ListView)findViewById(R.id.lvApps);

    // implement event when an item on list view is selected
    mListAppInfo.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView parent, View view, int pos, long id) {
            // get the list adapter
            AppInfoAdapter appInfoAdapter = (AppInfoAdapter)parent.getAdapter();
            // get selected item on the list
            ApplicationInfo appInfo = (ApplicationInfo)appInfoAdapter.getItem(pos);
            // launch the selected application
            Utilities.launchApp(parent.getContext(), getPackageManager(), appInfo.packageName);
        }

    });

    // implement event when an item on list view is selected via long-click for drag and drop
    mListAppInfo.setOnItemLongClickListener(new OnItemLongClickListener(){

        @Override
        public void onItemLongClick(AdapterView parent, View view,
                int pos, long id) {
            // TODO Auto-generated method stub
            // get the list adapter
            AppInfoAdapter appInfoAdapter = (AppInfoAdapter)parent.getAdapter();
            // get selected item on the list
            ApplicationInfo appInfo = (ApplicationInfo)appInfoAdapter.getItem(pos);
            // launch the selected application
            Utilities.launchApp(parent.getContext(), getPackageManager(), appInfo.packageName);
        }


    });
}
}

如您所见，我基本上是在设置长单击以执行与普通单击相同的操作，但我得到的错误是返回类型在这一行上是兼容的：

            public void onItemLongClick(AdapterView parent, View view,

快速修复告诉我将返回类型更改为布尔值(这是不对的)。

我怎么才能解决这个问题？

Answer 1

快速修复告诉我将返回类型更改为布尔值(这是不对的)。

为什么这样做不对？

根据医生的说法

快速修复是正确的。给它一个返回类型的boolean和return true。这让我们知道长时间的点击是成功的。
