activity左右滑动

        安卓机型杂乱，大部分的机子默认的activity在startActivity的时候都是默认从右往左进来的，但是如果有时候我们需要点击返回跳转到前面的activity，此时又是重新startActivity，为了使activity从左往右进来，就需要自己写两个简单的动画文件，然后利用overridePendingTransition方法设置。

第一步，先在res文件下新建一个anim文件夹

然后在anim文件夹下面写动画xml文件

代码示例：

R.anim.in_from_left.xml          从左边进

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="300"    android:fromXDelta="-100%p"    android:toXDelta="0%p" ></translate>

R.anim.out_to_right.xml         从右边出

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="300"    android:fromXDelta="0%p"    android:toXDelta="100%p" ></translate>

R.anim.in_from_right.xml         从右边进

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="300"    android:fromXDelta="100%p"    android:toXDelta="0%p" ></translate>

R.anim.out_to_left.xml         从左边出

<?xml version="1.0" encoding="utf-8"?><translate xmlns:android="http://schemas.android.com/apk/res/android"    android:duration="300"    android:fromXDelta="0%p"    android:toXDelta="-100%p" ></translate>

android:duration="300" 动画持续0.3秒 
android:fromXDelta="0" android:toXDelta="-100%p" 往左边消失
android:fromXDelta="-100%p" android:toXDelta="0" 从左边进
android:fromXDelta="0" android:toXDelta="100%p" 往右边消失
android:fromXDelta="100%p" android:toXDelta="0" 從右边进

ActivityOne代码

package com.Julia.activity;import com.Julia.testactivity.R;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;/** * @Title: ActivityOne.java * @Package * @Description: TODO(第一个activity) * @author XieHuiZhu [e-mail] * @date 2016-1-29 下午4:10:26 * @version V1.0 */public class ActivityOne extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_one);findViewById(R.id.jump_out_right).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent(ActivityOne.this, ActivityTwo.class);startActivity(intent);overridePendingTransition(R.anim.in_from_left, R.anim.out_to_right);finish();}});findViewById(R.id.jump_out_left).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent(ActivityOne.this, ActivityTwo.class);startActivity(intent);overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);finish();}});}}

ActivityOne的layout代码:activity_one.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:gravity="center"    android:orientation="vertical" >    <TextView        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginBottom="100dp"        android:gravity="center"        android:text="ActivityOne" />    <Button        android:id="@+id/jump_out_right"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="左进右出" />    <Button        android:id="@+id/jump_out_left"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="右进左出" /></LinearLayout>

ActivityTwo代码

/** * @Title: ActivityTwo.java  * @Package com.Julia.activity  * @Description: TODO(第二个activity)  * @author  XieHuiZhu [e-mail] * @date 2016-1-29 下午4:20:25  * @version V1.0    */package com.Julia.activity;import com.Julia.testactivity.R;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;public class ActivityTwo extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_two);findViewById(R.id.jump_in_left).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {startActivity(new Intent(ActivityTwo.this, ActivityOne.class));overridePendingTransition(R.anim.in_from_left, R.anim.out_to_right);finish();}});findViewById(R.id.jump_in_right).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {startActivity(new Intent(ActivityTwo.this, ActivityOne.class));overridePendingTransition(R.anim.in_from_right, R.anim.out_to_left);finish();}});}}

ActivityTwo的layout代码:activity_two.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:gravity="center"    android:orientation="vertical" >    <TextView        android:gravity="center"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="ActivityTwo"        android:layout_marginBottom="100dp" />    <Button        android:id="@+id/jump_in_left"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="左进右出" />    <Button        android:id="@+id/jump_in_right"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="右进左出" /></LinearLayout>

overridePendingTransition(进入的动画, 退出的动画);

如果前面的动画写了，后面的动画里面是空的文件，则跳转的时候背景是黑色的。
