通常我们使用popUpwindow的时候例如
先说一下思路，我们先定义一个basepopwindow,来抽象几个公用方法，然后通过子类来实现
具体代码：
A：抽象基类
public abstract class BasePopupWindow extends PopupWindow {
protected View popRootView;
public BasePopupWindow() {
super();
}
public BasePopupWindow(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public BasePopupWindow(Context context, AttributeSet attrs) {
super(context, attrs);
}
public BasePopupWindow(Context context) {
super(context);
}
public BasePopupWindow(int width, int height) {
super(width, height);
}
public BasePopupWindow(View contentView, int width, int height,
boolean focusable) {
super(contentView, width, height, focusable);
}
public BasePopupWindow(View contentView) {
super(contentView);
}
public BasePopupWindow(View contentView, int width, int height){
super(contentView, width, height,true);
this.popRootView = contentView;
setFocusable(true);
setOutsideTouchable(true);
setTouchable(true);
ColorDrawable dw = new ColorDrawable(0xb0000000);
this.setBackgroundDrawable(dw);
setAnimationStyle(R.style.AnimBottom);
initViews();
initEvents();
init();
}
public abstract void initViews();
public abstract void initEvents();
public abstract void init();
public View findViewById(int id) {
return popRootView.findViewById(id);
}
B: 实现子类：
里面加入我的一些说明：
public class CommBottomPopWindow extends BasePopupWindow implements
OnClickListener {
private Button cancleBtn;
private PopWindowListener listener;
private LinearLayout mLayout;
private Context mContext;
private boolean isHasSubTitle = false;
private LayoutInflater inflater;
/**
* 功能描述: 设置点击事件<br>
* 〈功能详细描述〉
* 点击的自定义回调接口
*/
public void setPopListener(PopWindowListener listener) {
this.listener = listener;
}
public CommBottomPopWindow(Context context) {
//布局填充
super((LayoutInflater.from(context).inflate(
R.layout.comm_bottom_popwindow, null)),
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
mContext = context;
}
/**
* 功能描述:初始化小标题 <br>
顶部是否需要提示的小标题
*/
public void initPopSubTitle(String notiTxt) {
mLayout.addView(createItem(notiTxt, true));
}
/**
* 功能描述: 初始化item<br>
* 〈功能详细描述〉
动态添加的条目
*/
public void initPopItem(List<String> list) {
if (list == null || list.size() == 0) {
return;
}
for (int i = 0; i < list.size(); i++) {
String title = list.get(i);
mLayout.addView(createItem(title, i, list.size()));
}
}
private View createItem(String itemTxt, boolean isSubTitle) {
return createItem(itemTxt, -1, -1, isSubTitle);
}
private View createItem(String itemTxt, final int index, int total) {
return createItem(itemTxt, index, total, false);
}
/**
* 功能描述: 创建item<br>
* 〈功能详细描述〉
*
创建具体的条目
*/
private View createItem(String itemTxt, final int index, int total,
boolean isSubTitle) {
inflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.comm_bottom_popwindow_item, null);
LinearLayout layout = (LinearLayout) view
.findViewById(R.id.comm_popwindow_item_layout);
TextView textView = (TextView) view
.findViewById(R.id.comm_popwindow_item_txt);
textView.setText(itemTxt);
if (isSubTitle) {
isHasSubTitle = true;
layout.setBackgroundResource(R.drawable.selectpopwin_up);
textView.setTextColor(ResUtil.getColor(R.color.color_999999));
} else if (index == 0 && !isHasSubTitle) {
layout.setBackgroundResource(R.drawable.btn_selectpopwin_up);
} else if (index == total - 1) {
layout.setBackgroundResource(R.drawable.btn_selectpopwin_down);
} else {
layout.setBackgroundResource(R.drawable.btn_camp_selpopwin_center);
}
view.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (index == -1) {
return;
}
if (listener != null) {
listener.onPopSelected(index);
}
}
});
return view;
}
@Override
public void initViews() {
mLayout = (LinearLayout) findViewById(R.id.comm_bottom_popwindow_layout);
cancleBtn = (Button) findViewById(R.id.camp_pop_cancle);
isHasSubTitle = false;
}
@Override
public void initEvents() {
cancleBtn.setOnClickListener(this);
popRootView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dismiss();
}
});
}
@Override
public void init() {
}
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.camp_pop_cancle:
dismiss();
break;
default:
break;
}
}
/**
* 功能描述: 显示pop window<br>
* 〈功能详细描述〉
*/
public void show(View view) {
showAtLocation(view, Gravity.BOTTOM, 0, 0);
}
//回调接口定义
public interface PopWindowListener {
public void onPopSelected(int which);
}
C：贴下布局
comm_bottom_popwindow.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:gravity="center_horizontal"
android:orientation="vertical"
android:paddingTop="20dp" >
<LinearLayout
android:id="@+id/comm_bottom_popwindow_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
<Button
android:id="@+id/camp_pop_cancle"
android:layout_width="fill_parent"
android:layout_height="@dimen/comm_padding_size_9"
android:layout_marginBottom="15dp"
android:layout_marginTop="15dp"
android:background="@drawable/btn_selectpopwin_cancel"
android:text="@string/camp_cancle"
android:textColor="@color/text_blue"
android:textSize="17sp" />
</LinearLayout>
</LinearLayout>
comm_bottom_popwindow_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/comm_popwindow_item_layout"
android:layout_width="fill_parent"
android:layout_height="@dimen/comm_padding_size_9"
android:gravity="center"
android:orientation="horizontal" >
<TextView
android:id="@+id/comm_popwindow_item_txt"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/camp_balance_query"
android:gravity="center"
android:textColor="@color/text_blue"
android:textSize="17sp" />
</LinearLayout>
其实就是定义一个linearlayout,根据具体的需求添加里面的item即可，同时通过一个自定义的接口监听item的点击就ok了
ps 用法如下:
private void initPopWindow() {
if (mPopWindow == null) {
mPopWindow = new CommBottomPopWindow(getActivity());
List<String> list = new ArrayList<>();
list.add("test1");
list.add("test2");
// 带显示小标题，可加可不加
mPopWindow.initPopSubTitle("sub title context");
mPopWindow.initPopItem(list);
mPopWindow.setPopListener(mPopListener);
}
// 显示pop window
mPopWindow.show(view);
}
