自定义布局实现仿qq侧滑部分Android代码，供大家参考，具体内容如下

源码DEMO地址：https://github.com/applelili/ImitationQQ

实现说明：

通过自定义布局实现：

SlidingLayout继承于 HorizontalScrollView

/*** Created by Administrator on 2017/3/29.*/public class SlidingLayout extends HorizontalScrollView{/** 左侧右边间距 */private float rightPadding;/** 左侧菜单的宽度 */private int leftWidth;private ViewGroup leftView;private ViewGroup contentView;private final Context context;private boolean isOpenMeun = true;private ImageView shadowView;public SlidingLayout(Context context) {this(context,null);}public SlidingLayout(Context context, AttributeSet attrs) {this(context, attrs,0);}public SlidingLayout(Context context, AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);this.context = context;//获取自定义的属性TypedArray typedArray=context.obtainStyledAttributes(attrs,R.styleable.SlidingLayout);rightPadding=typedArray.getDimension(R.styleable.SlidingLayout_rightPadding,80);//计算左侧菜单的宽度leftWidth = (int) (getScreenWidth() - rightPadding + 0.5f);}//获取屏幕的宽度private float getScreenWidth() {return getResources().getDisplayMetrics().widthPixels;}@Override /** 布局解析完毕的时候 */protected void onFinishInflate() {super.onFinishInflate();ViewGroup container= (ViewGroup) getChildAt(0);if(container.getChildCount() > 2){throw new IllegalStateException("SlidingLayout中只能放两个子View");}//获取左侧菜单viewleftView = (ViewGroup) container.getChildAt(0);//获取主布局的ViwecontentView = (ViewGroup) container.getChildAt(1);//设置子view 的宽度leftView.getLayoutParams().width = leftWidth;contentView.getLayoutParams().width = (int) getScreenWidth();//移除父布局container.removeView(contentView);FrameLayout frameLayout=new FrameLayout(context);frameLayout.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));frameLayout.addView(contentView);//添加阴影shadowView = new ImageView(context);shadowView.setBackgroundColor(Color.parseColor("#99000000"));frameLayout.addView(shadowView);container.addView(frameLayout);}/*** 该方法在滑动的时候会不断的调用* @param l : left* @param t* @param oldl* @param oldt*/@Overrideprotected void onScrollChanged(int l, int t, int oldl, int oldt) {super.onScrollChanged(l, t, oldl, oldt);float x=l*0.8f;//偏移量leftView.setTranslationX(x);//平移float color = 1 - l * 1.0f / leftWidth;shadowView.setAlpha(color);}@Overridepublic boolean onTouchEvent(MotionEvent ev) {switch (ev.getAction()) {case MotionEvent.ACTION_UP://手指抬起的时候判断是否关闭int currentX = getScrollX();if (isOpenMeun) {if (currentX >= leftWidth / 2) {closeMeun();} else {openMeun();}//点击关闭float x = ev.getX();if (x > leftWidth) {closeMeun();}return true;} else {//关闭状态if (currentX < leftWidth / 2) {openMeun();} else {closeMeun();}return true;}}return super.onTouchEvent(ev);}/** 关闭菜单 */public void closeMeun(){isOpenMeun = false;smoothScrollTo(leftWidth,0);// 250ms}/** 打开菜单 */public void openMeun(){isOpenMeun = true;smoothScrollTo(0,0);}}

attrs属性文件

<?xml version="1.0" encoding="utf-8"?><resources><declare-styleable name="SlidingLayout"> <attr name="rightPadding" format="dimension"/></declare-styleable></resources>

布局方面

<?xml version="1.0" encoding="utf-8"?><com.example.myqq.SlidingLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" app:rightPadding="65dp" tools:context="com.example.myqq.MainActivity"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal"> <include layout="@layout/left_main" /> <include layout="@layout/right_main" /> </LinearLayout></com.example.myqq.SlidingLayout>

activity

package com.example.myqq;import android.animation.ObjectAnimator;import android.annotation.TargetApi;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.WindowManager;import android.widget.ArrayAdapter;import android.widget.ImageView;import android.widget.ListView;public class MainActivity extends AppCompatActivity { private String strings[] = {"开通会员", "QQ钱包", "个性装扮", "我的收藏", "我的相册", "我的文件", "我的日程", "我的名片夹"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setState(); setContentView(R.layout.activity_main); ListView listView= (ListView) findViewById(R.id.list_left); listView.setDividerHeight(0); listView.setAdapter(new ArrayAdapter<>(this,android.R.layout.simple_list_item_1,strings)); ImageView bgimg1= (ImageView) findViewById(R.id.bgimg); float currentY=bgimg1.getTranslationY(); ObjectAnimator animator = ObjectAnimator.ofFloat(bgimg1, "translationY", currentY, -100, -40, currentY); animator.setDuration(5000); animator.setRepeatCount(ObjectAnimator.INFINITE); animator.start(); } @TargetApi(20) private void setState() { WindowManager.LayoutParams params=new WindowManager.LayoutParams(); params.flags=WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS; getWindow().setAttributes(params); }}
