ListView弹出窗口

Question

我正在制作一个应用程序并使用ListView的自定义适配器。它是在活动

public class Adapter extends ArrayAdapter { 
    Context mContext; 
    int resourceID; 
    ArrayList<String> names; 
    public Adapter(Context context, int resource, ArrayList<String> objects) { 
     super(context, resource, objects); 
     this.mContext = context; 
     this.resourceID=resource; 
     this.names= objects; 
    } 

    @Override 
    public String getItem(int position) { 
     return names.get(position); 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View row = convertView; 
     LayoutInflater inflater = LayoutInflater.from(mContext); 
     row = inflater.inflate(resourceID, parent, false); 

     TextView text = (TextView) row.findViewById(R.id.text); 

     text.setText(names.get(position)); 
     return row; 
    } 

} 

工作，我用这个代码，使他们出现在活动

myNames= (ListView) findViewById(R.id.List); 
    adapter = new Adapter(this,R.layout.names_view, Current.Names); 
    myNames.setAdapter(adapter); 

现在我想点击一个按钮，使同一列表出现在弹出窗口中，任何帮帮我？

Answer 1

你可以做如下：

1）创建自定义点击按钮上的对话框：

Button clickButton = (Button) findViewById(R.id.clickButton); 
clickButton.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
     final Dialog dialog = new Dialog(YourActivity.this); 
     dialog.setContentView(R.layout.custom_dialog); 
     dialog.setTitle("Title..."); 
     myNames= (ListView) dialog.findViewById(R.id.List); 
     adapter = new Adapter(YourActivity.this,R.layout.names_view, Current.Names); 
     myNames.setAdapter(adapter); 
     dialog.show(); 
     } 
    }); 

2）添加在对话框布局列表视图（custom_dialog.xml）：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <ListView 
     android:id="@+id/List" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" > 
    </ListView> 

</LinearLayout> 

Answer 2

可以使用自定义对话框

定制对话框mydialog.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content"> 
<ListView 
    android:id="@+id/lv" 
    android:layout_width="wrap_content" 
    android:layout_height="fill_parent"/> 
</LinearLayout> 

在你的活动

Dialog dialog = new Dialog(Activity.this); 
    dialog.setContentView(R.layout.mydialog) 
ListView lv = (ListView) dialog.findViewById(R.id.lv); 
dialog.setCancelable(true); 
dialog.setTitle("ListView"); 
dialog.show(); 

Answer 3

custom.xml

<?xml version="1.0" encoding="utf-8"?> 
<ListView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/listView1" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

</ListView> 

活动

String names[] ={"A","B","C","D"}; 
       AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this); 
       LayoutInflater inflater = getLayoutInflater(); 
       View convertView = (View) inflater.inflate(R.layout.custom, null); 
       alertDialog.setView(convertView); 
       alertDialog.setTitle("List"); 
       ListView lv = (ListView) convertView.findViewById(R.id.List); 
       Adapter<String> adapter = new Adapter(this,R.layout.names_view, Current.Names); 
       lv.setAdapter(adapter); 
       alertDialog.show(); 

Answer 4

我输入 “PopupWindow”进入谷歌，发现这个：

直到现在我还不知道PopupWindow，我建议使用一个对话框，例如具有Costum视图的AlertDialog。

我希望我能帮忙！
