Android PopupWindow 仿微信弹出效果
项目中，我需要PopupWindow的时候特别多，这个东西也特别的好使，所以我今天给大家写一款PopupWindow 仿微信弹出效果，这样大家直接拿到项目里就可以用了！首先让我们先看效果：
那么我首先先看下布局代码非常简单：如下
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pop_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/bg_pulish"
android:gravity="center"
android:orientation="vertical" >
<Button
android:id="@+id/btn_hand"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="20dip"
android:background="@drawable/bg_publish_product_selector"
android:text="1"
android:textStyle="bold" />
<Button
android:id="@+id/btn_library"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="20dip"
android:background="@drawable/bg_publish_product_selector"
android:text="2"
android:textStyle="bold" />
<Button
android:id="@+id/btn_two_code"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="20dip"
android:background="@drawable/bg_publish_product_selector"
android:text="3"
android:textStyle="bold" />
<Button
android:id="@+id/btn_cancel"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="20dip"
android:layout_marginRight="20dip"
android:layout_marginTop="30dip"
android:layout_marginBottom="30dp"
android:background="@drawable/bg_publish_product_selector"
android:text="取消"
android:textStyle="bold" />
</LinearLayout>下面我们来看核心的代码，如下
package com.example.showpopupwindow;
import android.app.Activity;
import android.content.Context;
import android.graphics.drawable.ColorDrawable;
import android.view.LayoutInflater;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnTouchListener;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.PopupWindow;
public class PublishSelectPicPopupWindow extends PopupWindow {
private Button btnHand;
private Button btnLibrary;
private Button btnTwocode;
private Button btnCancel;
private View mMenuView;
@SuppressWarnings("deprecation")
public PublishSelectPicPopupWindow(Activity context,OnClickListener itemsOnClick) {
super(context);
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mMenuView = inflater.inflate(R.layout.publish_dialog, null);
btnHand = (Button) mMenuView.findViewById(R.id.btn_hand);
btnLibrary = (Button) mMenuView.findViewById(R.id.btn_library);
btnTwocode=(Button) mMenuView.findViewById(R.id.btn_two_code);
btnCancel = (Button) mMenuView.findViewById(R.id.btn_cancel);
btnCancel.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dismiss();
}
});
//设置按钮监听
btnHand.setOnClickListener(itemsOnClick);
btnLibrary.setOnClickListener(itemsOnClick);
btnTwocode.setOnClickListener(itemsOnClick);
btnCancel.setOnClickListener(itemsOnClick);
//设置SelectPicPopupWindow的View
this.setContentView(mMenuView);
//设置SelectPicPopupWindow弹出窗体的宽
this.setWidth(LayoutParams.FILL_PARENT);
//设置SelectPicPopupWindow弹出窗体的高
this.setHeight(LayoutParams.WRAP_CONTENT);
//设置SelectPicPopupWindow弹出窗体可点击
this.setFocusable(true);
//设置SelectPicPopupWindow弹出窗体动画效果
this.setAnimationStyle(R.style.AnimBottom);
//实例化一个ColorDrawable颜色为半透明
ColorDrawable dw = new ColorDrawable(0xb0000000);
//设置SelectPicPopupWindow弹出窗体的背景
this.setBackgroundDrawable(dw);
//mMenuView添加OnTouchListener监听判断获取触屏位置如果在选择框外面则销毁弹出框
mMenuView.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
int height = mMenuView.findViewById(R.id.pop_layout).getTop();
int y=(int) event.getY();
if(event.getAction()==MotionEvent.ACTION_UP){
if(y<height){
dismiss();
}
}
return true;
}
});
}
}
我们在MainActivity调用我们写好的代码 如下：
package com.example.showpopupwindow;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Gravity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends Activity {
private PublishSelectPicPopupWindow menuWindow;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button button=(Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// 实例化SelectPicPopupWindow
menuWindow = new PublishSelectPicPopupWindow(MainActivity.this,itemsOnClick);
// 显示窗口
menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.button1),
Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
}
});
}
// 为弹出窗口实现监听类
private OnClickListener itemsOnClick = new OnClickListener() {
public void onClick(View v) {
menuWindow.dismiss();
switch (v.getId()) {
case R.id.btn_hand:
Toast.makeText(MainActivity.this, "1", 2).show();
break;
case R.id.btn_two_code:
Toast.makeText(MainActivity.this, "2", 2).show();
break;
case R.id.btn_library:
Toast.makeText(MainActivity.this, "3", 2).show();
break;
default:
break;
}
}
};
}
图片资源我会随源码一起给你们，下载吧，直接用到项目，简单高效哈哈
