Android实现自定义AlertDialog的自下向上的动画效果(并消除dialog边框)

话不多说，直接上代码：

代码语言：javascript复制

AlertDialog.Builder builder = new Builder(HomeActivity.this);
				View view = View.inflate(HomeActivity.this, R.layout.home_add_dialog, null);
				btn_add_cancel = (Button) view.findViewById(R.id.btn_add_cancel);
				builder.setView(view);
				dialog = builder.create();
				//消除dialog黑色边框
				dialog.setView(view,0,0,0,0);
				dialog.show();
//				overridePendingTransition(R.anim.hor_tran_in, R.anim.hor_tran_out);
				//设置大小  
		        WindowManager.LayoutParams layoutParams = dialog.getWindow().getAttributes();  
		        layoutParams.width = LayoutParams.MATCH_PARENT;  
		        layoutParams.height = LayoutParams.MATCH_PARENT;  
		        dialog.getWindow().setAttributes(layoutParams); 
		        //设置dialog进入的动画效果
		       <span style="color:#33ff33;"> Window window = dialog.getWindow();
		        window.setWindowAnimations(R.style.mystyle);</span>

先在图片对应values/styles.xml中新建个style，名称为mystyle：

代码语言：javascript复制

<style name="mystyle" parent="android:Animation">
        <item name="@android:windowEnterAnimation">@anim/ver_tran_in</item>
        <item name="@android:windowExitAnimation">@anim/ver_tran_out</item>
 </style>

而其中的anim/ver_tran_in内容如下：

代码语言：javascript复制

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="500"
    android:fromXDelta="0"
    android:toXDelta="0"
    android:fromYDelta="80%p"
    android:toYDelta="0" >
    
</translate>

anim/ver_tran_out内容：

代码语言：javascript复制

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="500"
    android:fromXDelta="0"
    android:toXDelta="0"
    android:fromYDelta="0"
    android:toYDelta="-100%p" >
    
</translate>
