一、概述
在上一篇博文中,博文地址Android-通过SlidingPaneLayout高仿微信6.2最新版手势滑动返回(一),我们是通过官方自带的SlidingPaneLayout来实现的手势滑动返回。在这篇博文中,我们将採用SlidingMenu来高仿。
事实上实现的原理都一样。仅仅只是是把SlidingPaneLayout换成SlidingMenu而已,只是SlidingMenu本身的功能比官方自带的强大,不仅能够实现像微信一样的边缘滑动返回,还支持全屏幕滑动返回。
你还能够加入动画效果。只是这里笔者业务时间不多。这里就没有实现!
首先来看一下效果图,一个是边缘滑动的,一个是全屏幕滑动,效果很赞。比我们上一篇博文中实现的还要给力些!
- 边缘滑动效果图
- 全屏幕滑动效果图
以下我们从头開始一步一步来实现这个手势滑动返回效果,从新建project到引入SlidingMenu,然后通过改动Activity主题样式、抽取出实现SwipeBack的父类BaseSwipeBackActivity等等
二、以下開始进入主题
首先肯定是通过AndroidStudio新建一个SlidingMenuSwipeBackDemoproject,然后把下好的SlidingMenu库移到项目中,在settings.gradle文件加入这个库,并在app内的build.gradle加入这个库依赖
settings.gradle
include ‘:app’
include ‘:SlidingLibrary’
app内的build.gradle
compile project(":SlidingLibrary")
这里我把SlidingMenu的库名称改成SlidingLibrary了。项目就差点儿相同建好了,见效果图:
下一步就是把我们上个博文中的一些用到的资源文件拷过来,如须要用到的动画资源slide_in_right.xml、slide_out_right.xml、styles.xml,这里初略的展示下styles.xml文件内容,代码例如以下:
<style name="JK.SwipeBack.Transparent.Theme" parent="AppTheme">
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowAnimationStyle">@style/JK.Animation.SlidingBack</item>
<item name="android:actionBarStyle">@style/JKActionBar.Custom</item>
</style>
<style name="JKActionBar.Custom" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
<item name="displayOptions">showCustom</item>
<item name="android:background">@android:color/transparent</item>
<item name="background">@android:color/transparent</item>
<item name="android:displayOptions" tools:ignore="NewApi">showCustom</item>
<item name="android:height">?actionBarSize</item>
</style>
<style name="JK.Animation.SlidingBack" parent="@android:style/Animation.Activity">
<item name="android:activityOpenEnterAnimation">@anim/slide_in_right</item>
<item name="android:activityOpenExitAnimation">@anim/slide_out_right</item>
<item name="android:activityCloseEnterAnimation">@anim/slide_in_right</item>
<item name="android:activityCloseExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperOpenEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperOpenExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperCloseEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperCloseExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperIntraOpenEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperIntraOpenExitAnimation">@anim/slide_out_right</item>
<item name="android:wallpaperIntraCloseEnterAnimation">@anim/slide_in_right</item>
<item name="android:wallpaperIntraCloseExitAnimation">@anim/slide_out_right</item>
</style>
接下来我们创建BaseSwipeBackActivity这个基类。全部实现手势滑动返回的类继承自它就OK了,不须要手势滑动的不须要继承它。大招来了,看BaseSwipeBackActivity源代码文件。由于代码凝视的比較具体,这里我就直接贴代码了,代码很的简单
package com.hhl.slidingmenuswipebackdemo;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.KeyEvent;
import android.view.View;
import android.view.ViewGroup;
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingActivityHelper;
/**
* Created by hailonghan on 15/6/11.

public abstract class BaseSwipeBackActivity extends AppCompatActivity implements SlidingMenu.OnOpenedListener {
private SlidingActivityHelper mHelper;
//SlidingMenu
private SlidingMenu mSlidingMenu;
@Override
protected void onCreate(Bundle savedInstanceState) {
mHelper = new SlidingActivityHelper(this);
mHelper.onCreate(savedInstanceState);
//这里借用了SlidingMenu的setBehindContentView方法来设置一个透明菜单
View behindView = new View(this);
behindView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
behindView.setBackgroundColor(getResources().getColor(android.R.color.transparent));
setBehindContentView(behindView);
mSlidingMenu = getSlidingMenu();
//设置阴影宽度为10个px
mSlidingMenu.setShadowWidth(10);
//设置阴影
mSlidingMenu.setShadowDrawable(R.drawable.slide_shadow);
//设置以下的布局,也就是我们上面定义的透明菜单离右边屏幕边缘的距离为0,也就是滑动开以后菜单会全屏幕显示
mSlidingMenu.setBehindOffset(0);
mSlidingMenu.setFadeDegree(0.35f);
//菜单打开监听。由于菜单打开后我们要finish掉当前的Activity
mSlidingMenu.setOnOpenedListener(this);
//设置手势滑动方向。由于我们要实现微信那种右滑动的效果,这里设置成SlidingMenu.LEFT模式
mSlidingMenu.setMode(SlidingMenu.LEFT);
//由于微信是仅仅有边缘滑动。我们设置成TOUCHMODE_MARGIN模式,假设你想要全屏幕滑动,仅仅须要把这个改成TOUCHMODE_FULLSCREEN就OK了
mSlidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
super.onCreate(savedInstanceState);
}
@Override
public void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mHelper.onPostCreate(savedInstanceState);
}
@Override
public boolean onSupportNavigateUp() {
return true;
}
@Override
public View findViewById(int id) {
View v = super.findViewById(id);
if (v != null)
return v;
return mHelper.findViewById(id);
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mHelper.onSaveInstanceState(outState);
}
@Override
public void setContentView(int id) {
setContentView(getLayoutInflater().inflate(id, null));
}
@Override
public void setContentView(View v) {
setContentView(v, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
}
@Override
public void setContentView(View v, ViewGroup.LayoutParams params) {
super.setContentView(v, params);
mHelper.registerAboveContentView(v, params);
}
public void setBehindContentView(int id) {
setBehindContentView(getLayoutInflater().inflate(id, null));
}
public void setBehindContentView(View v) {
setBehindContentView(v, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
}
public void setBehindContentView(View v, ViewGroup.LayoutParams params) {
mHelper.setBehindContentView(v, params);
}
public SlidingMenu getSlidingMenu() {
return mHelper.getSlidingMenu();
}
public void toggle() {
mHelper.toggle();
}
public void showContent() {
mHelper.showContent();
}
public void showMenu() {
mHelper.showMenu();
}
public void showSecondaryMenu() {
mHelper.showSecondaryMenu();
}
public void setSlidingActionBarEnabled(boolean b) {
mHelper.setSlidingActionBarEnabled(b);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
boolean b = mHelper.onKeyUp(keyCode, event);
if (b) return b;
return super.onKeyUp(keyCode, event);
}
//滑动全然打开菜单后结束掉当前的Activity
@Override
public void onOpened() {
this.finish();
}
@Override
public void finish() {
super.finish();
this.overridePendingTransition(0, R.anim.slide_out_right);
}
}
这里须要注意的是。你假设想要边缘滑动返回,仅仅须要将SlidingMenu的滑动模式改成TOUCHMODE_MARGIN就能够了,全屏幕滑动的话改成TOUCHMODE_FULLSCREEN就OK了
写到这基本上就差点儿相同了,我感觉没啥难度的,就是把Activity的样式改成透明,抽取出一个父类BaseSwipeBackActivity。在父类里面加入SlidingMenu。将左菜单设置成透明,然后菜单全然打开后finish掉当前的Activity
