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：

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：

<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：

<?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：

<?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>
