Android PopupWindow 仿微信彈出效果

項目中，我需要PopupWindow的時候特別多，這個東西也特別的好使，因此我今天給你們寫一款PopupWindow 仿微信彈出效果。這樣你們直接拿到項目裏就可以用了！

首先讓咱們先看效果：

那麼我首先先看下佈局代碼很easy：例如如下

<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>

如下咱們來看核心的代碼。例如如下

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();
			}
		});
		//設置button監聽
		btnHand.setOnClickListener(itemsOnClick);
		btnLibrary.setOnClickListener(itemsOnClick);
		btnTwocode.setOnClickListener(itemsOnClick);
		btnCancel.setOnClickListener(itemsOnClick);
		//設置SelectPicPopupWindow的View
		this.setContentView(mMenuView);
		//設置SelectPicPopupWindow彈出窗口的寬
		this.setWidth(LayoutParams.FILL_PARENT);
		//設置SelectPicPopupWindow彈出窗口的高
		this.setHeight(LayoutParams.WRAP_CONTENT);
		//設置SelectPicPopupWindow彈出窗口可點擊
		this.setFocusable(true);
		//設置SelectPicPopupWindow彈出窗口動畫效果
		this.setAnimationStyle(R.style.AnimBottom);
		//實例化一個ColorDrawable顏色爲半透明
		ColorDrawable dw = new ColorDrawable(0xb0000000);
		//設置SelectPicPopupWindow彈出窗口的背景
		this.setBackgroundDrawable(dw);
		//mMenuView加入OnTouchListener監聽推斷獲取觸屏位置假設在選擇框外面則銷燬彈出框
		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;
			}
		});

	}

}

咱們在MainActivity調用咱們寫好的代碼 例如如下：

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) {
				// 實例化SelectPicPopupWindow
				menuWindow = new PublishSelectPicPopupWindow(MainActivity.this,itemsOnClick);
				// 顯示窗體
				menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.button1),
						Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0);
			}
		});
	}
	// 爲彈出窗體實現監聽類
		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;
				}

			}
		};

}

圖片資源我會隨源代碼一塊兒給大家，下載吧。直接用到項目，簡單高效哈哈
