android仿微信的開門效果

有人已經發過了，我掐頭去尾精簡了一下 

 

 
這種效果跟圖和布局有很大關係，並不難。 

先看布局： 

<?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:orientation="vertical" >    <LinearLayout         android:id="@+id/layout"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:orientation="vertical"        android:background="@drawable/whatsnew_bg"        android:gravity="center_horizontal|bottom"        android:visibility="visible"        >        <Button              android:id="@+id/btn_start"              android:layout_width="wrap_content"              android:layout_height="wrap_content"              android:text="開始我的性生活"              android:textSize="18sp"              android:textColor="#FFFFFFFF"              android:background="@drawable/button_bg"  android:layout_marginBottom="20dip"              />    </LinearLayout>    <LinearLayout         android:id="@+id/animLayout"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:orientation="horizontal"        >        <LinearLayout            android:id="@+id/leftLayout"             android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:layout_weight="1"            >        <ImageView             android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:src="@drawable/whatsnew_left"            android:layout_weight="1"            />        <ImageView             android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/whatsnew_left_m"            />        </LinearLayout>        <LinearLayout             android:id="@+id/rightLayout"             android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:layout_weight="1"            >        <ImageView             android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@drawable/whatsnew_right_m"            />        <ImageView             android:layout_width="fill_parent"            android:layout_height="wrap_content"            android:src="@drawable/whatsnew_right"            android:layout_weight="1"            />        </LinearLayout>    </LinearLayout></LinearLayout>

在看代碼： 

package com.dl.app;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.view.animation.Animation.AnimationListener;import android.widget.Button;import android.widget.LinearLayout;public class TestOpenDoorActivity extends Activity {private Context context;private Button btn_start;private LinearLayout layout;private LinearLayout animLayout;private LinearLayout leftLayout;private LinearLayout rightLayout;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        this.context=this;        initViews();            }        private void initViews(){    btn_start=(Button)findViewById(R.id.btn_start);    btn_start.setOnClickListener(onClickListener);        layout = (LinearLayout) findViewById(R.id.layout);    animLayout = (LinearLayout) findViewById(R.id.animLayout);leftLayout  = (LinearLayout) findViewById(R.id.leftLayout);rightLayout  = (LinearLayout) findViewById(R.id.rightLayout);    }        View.OnClickListener onClickListener=new View.OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch (v.getId()) {case R.id.btn_start:doOpenDoor();break;default:break;}}        };        private void doOpenDoor(){        layout.setVisibility(View.GONE);    animLayout.setVisibility(View.VISIBLE);    Animation leftOutAnimation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.translate_left);Animation rightOutAnimation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.translate_right);leftLayout.setAnimation(leftOutAnimation);rightLayout.setAnimation(rightOutAnimation);leftOutAnimation.setAnimationListener(new AnimationListener() {@Overridepublic void onAnimationStart(Animation animation) {}@Overridepublic void onAnimationRepeat(Animation animation) {}@Overridepublic void onAnimationEnd(Animation animation) {leftLayout.setVisibility(View.GONE);rightLayout.setVisibility(View.GONE);Intent intent = new Intent(context,OtherActivity.class);startActivity(intent);finish();overridePendingTransition(R.anim.zoom_out_enter, R.anim.zoom_out_exit);}});    }}
