新闻类客户端第一天——splash和sliding menu库导入

新闻类客户端第一天——splash和sliding menu库导入

一.splash页面并进入主界面
*布局：*

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/rl_root"  android:background="@drawable/background_splash"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.administrator.xw.SplashActivity">    <ImageView        android:id="@+id/imageView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_centerVertical="true"        android:src="@drawable/background_splash" /></RelativeLayout>

逻辑

public class SplashActivity extends Activity {    private RelativeLayout rlRoot;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_splash);        rlRoot = (RelativeLayout) findViewById(R.id.rl_root);        // 旋转动画        RotateAnimation animRotate = new RotateAnimation(0, 360,                Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,                0.5f);        animRotate.setDuration(1000);// 动画时间        animRotate.setFillAfter(true);// 保持动画结束状态        // 缩放动画        ScaleAnimation animScale = new ScaleAnimation(0, 1, 0, 1,                Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,                0.5f);        animScale.setDuration(1000);        animScale.setFillAfter(true);// 保持动画结束状态        // 渐变动画        AlphaAnimation animAlpha = new AlphaAnimation(0, 1);        animAlpha.setDuration(2000);// 动画时间        animAlpha.setFillAfter(true);// 保持动画结束状态        // 动画集合        AnimationSet set = new AnimationSet(true);        set.addAnimation(animRotate);        set.addAnimation(animScale);        set.addAnimation(animAlpha);        // 启动动画        rlRoot.startAnimation(set);        set.setAnimationListener(new Animation.AnimationListener() {            @Override            public void onAnimationStart(Animation animation) {            }            @Override            public void onAnimationRepeat(Animation animation) {            }            @Override            public void onAnimationEnd(Animation animation) {                // 动画结束,跳转页面                // 如果是第一次进入, 跳新手引导                   Intent intent = new Intent(getApplicationContext(),                            MainActivity.class);                startActivity(intent);                finish();// 结束当前页面            }        });    }}

二.左滑sliding menu
首先导入sliding menu库
步骤：1.改sliding menu中library为slidingmenulibrary
2.File–Import Module导入
3.修改SlidingMenu里的build.gradle文件（视自己个人情况改动）

buildscript {    repositories {        mavenCentral()    }    dependencies {        classpath 'com.android.tools.build:gradle:2.0.0'    }}apply plugin: 'android-library'dependencies {    compile 'com.android.support:support-v4:2.2.2'//改动    compile 'com.android.support:appcompat-v7:24.2.1'//改动}android {    compileSdkVersion 24//改动    buildToolsVersion "24.0.3"//改动    defaultConfig {        minSdkVersion 23//改动        targetSdkVersion 24//改动    }

4.修改app目录下的build.gradle文件

dependencies {    compile fileTree(dir: 'libs', include: ['*.jar'])    compile 'com.android.support:appcompat-v7:21.0.3'    compile project(':SlidingMenu')//加上这句～}

5.万一出现（float）FloatMath错误，将其改为（float）Math

三.开始写左滑栏left_menu
布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="#ff0000"></LinearLayout>

逻辑

setBehindContentView(R.layout.left_menu);        SlidingMenu slidingMenu = getSlidingMenu();        slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);//全屏触摸        slidingMenu.setBehindOffset(200);//屏幕预留200像素宽度**四.去掉标题栏**必须要在setContentView上面

requestWindowFeature(Window.FEATURE_NO_TITLE);// 去掉标题,
