android - 返回类型与 AdapterView.OnItemLongClickListener.onItemLongClick(AdapterView, View, int, long) 不兼容

Question

在我的小部件中，当 ListView 中的一个项目被长按时，我希望启动该项目(然而，在我目前的编码中，正常的点击也可以做到这一点，但现在我正在让长按做一些事情这样我就可以设置它以供以后需要更改长按的功能时使用)。

这是我的代码:

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，我基本上是将长按设置为执行与普通点击相同的操作，但我收到返回类型兼容的错误消息:

            public void onItemLongClick(AdapterView parent, View view,

快速修复告诉我将返回类型更改为 bool 值(这是不正确的)。

我该如何解决这个问题？

Answer 1

Quick fix tells me to change the return type to boolean (which isn't right).

为什么不对？

According to the Docs

快速修复是正确的。给它一个返回类型 boolean 和 return true。这让它知道长按成功。
