基于上一篇实现的SimpleListPopupWindow<T>

这次是个简单的PopupWindow，快速迭代用。

import java.util.List;

import android.content.Context;
import android.view.View;
import android.widget.AdapterView;
import android.widget.LinearLayout.LayoutParams;
import android.widget.ListView;
import android.widget.PopupWindow;

import com.mb.bgfitting.App;
import com.mb.bgfitting.CommonAdapter;
import com.mb.bgfitting.ViewHolder;
import com.mb.bgfitting.app.R;

/**

public class SimpleListPopupWindow<T> extends PopupWindow {

  private Context context;
  private CommonAdapter<T> adapter;
  private List<T> beans;
  public SimpleListPopupWindow(Context context, View view, int width,List<T> b) {
    super(view, width, LayoutParams.WRAP_CONTENT, true);
    this.context = context;
    this.beans = b;
    this.setBackgroundDrawable(App.res.getDrawable(R.drawable.bg_popupwindow));
    this.setOutsideTouchable(true);
    this.setAnimationStyle(android.R.style.Animation_Dialog);
    // this.update();
    // this.setTouchable(true);
    // this.setFocusable(false);

    ListView listView = (ListView) view.findViewById(R.id.listView);
    listView.setAdapter(adapter = new CommonAdapter<T>(context, beans,R.layout.item_for_popupwindow_simple) {
      @Override
      public void setValues(ViewHolder helper, T item, int position) {
        helper.setText(R.id.item_0, item.toString());
      }
    });

    listView.setOnItemClickListener(new ListView.OnItemClickListener() {

      @Override
      public void onItemClick(AdapterView<?> pearnt, View view,
          int position, long id) {
        // TODO Auto-generated method stub
        dismiss();
        if (onItemClickListener != null) {
          onItemClickListener.onItemClick(position,beans.get(position));
        }
      }
    });

  }

  public interface OnItemClickListener<T> {
    void onItemClick(int position, T item);
  }

  OnItemClickListener<T> onItemClickListener;

  public void setOnItemClickListener(OnItemClickListener<T> onItemClickListener) {
    this.onItemClickListener = onItemClickListener;
  }

}

一个简单的Item：item_for_popupwindow_simple.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <TextView 
        android:id="@+id/item_0"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingTop="8dp"
        android:paddingBottom="8dp"
        android:gravity="center"
        android:textColor="@color/base_text_black"
        android:textSize="@dimen/font_middle"
        android:singleLine="true"
        />

</RelativeLayout>

用法：

private void showPopWindow(List<String> list) {
    View view = LayoutInflater.from(context).inflate(R.layout.popupwindow_simple, null);
    final SimpleListPopupWindow<String> popupWindow = new SimpleListPopupWindow<String>(context,view, btn_appointmentIndex.getWidth(), list);
    popupWindow.showAsDropDown(btn_appointmentIndex, 0, 0);
    popupWindow.setOnItemClickListener(new SimpleListPopupWindow.OnItemClickListener<String>() {

      @Override
      public void onItemClick(int position,final String item) {
        // TODO Auto-generated method stub

      }
    });
  }

popupwindow_simple.xml:

<?xml version="1.0" encoding="utf-8"?>
<ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/listView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:cacheColorHint="@android:color/transparent"
    android:listSelector="@color/base_gray"
    />
