一个典型的从下部弹上来的Dialog

典型的看图

import android.app.Dialog;import android.content.Context;import android.os.Bundle;import android.util.DisplayMetrics;import android.view.Gravity;import android.view.View;import android.view.Window;import android.view.WindowManager;import cn.tangdada.tangbang.R;public class SimpleBottomDialog extends Dialog{    private Context context;    public SimpleBottomDialog(Context context)    {        this(context, R.style.Theme_Dialog_From_Bottom);        // TODO Auto-generated constructor stub    }    public SimpleBottomDialog(Context context, int theme)    {        super(context, theme);        // TODO Auto-generated constructor stub        this.context = context;        init();    }    private void init()    {        this.setCanceledOnTouchOutside(true);        this.setCancelable(true);    }    @Override    protected void onCreate(Bundle savedInstanceState)    {        // TODO Auto-generated method stub        super.onCreate(savedInstanceState);        setContentView(R.layout.dialog_simple_bottom);        initViews();        initValues();    }    private void initViews()    {        findViewById(R.id.btn_0).setOnClickListener(clickListener);        findViewById(R.id.btn_1).setOnClickListener(clickListener);    }    private void initValues()    {        // 不能写在init()中        Window window = getWindow();        WindowManager.LayoutParams lp = window.getAttributes();        DisplayMetrics dm = context.getResources().getDisplayMetrics();        lp.width = dm.widthPixels;//让dialog的宽占满屏幕的宽        lp.gravity = Gravity.BOTTOM;//出现在底部        window.setAttributes(lp);    }    View.OnClickListener clickListener = new View.OnClickListener()    {        @Override        public void onClick(View v)        {            // TODO Auto-generated method stub            switch (v.getId())            {                case R.id.btn_0:                    if (onOKClickListener != null)                    {                        onOKClickListener.onOKClick(v);                    }                    dismiss();                    break;                case R.id.btn_1:                    dismiss();                    break;                default:                    break;            }        }    };    private OnOKClickListener onOKClickListener;    public interface OnOKClickListener    {        public void onOKClick(View v);    }    public void setOnOKClickListener(OnOKClickListener onOKClickListener)    {        this.onOKClickListener = onOKClickListener;    }}

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:gravity="center_vertical"    android:orientation="vertical"    android:padding="@dimen/padding" >    <Button        android:id="@+id/btn_0"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginBottom="@dimen/margin"        android:background="@drawable/bg_btn_white_blue_with_corner"        android:padding="@dimen/padding"        android:text="@string/send" />    <Button        android:id="@+id/btn_1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:background="@drawable/bg_btn_white_blue_with_corner"        android:padding="@dimen/padding"        android:text="@string/cancel" /></LinearLayout>

样式：

<style name="Theme_Dialog_From_Bottom" parent="@android:style/Theme.Dialog">        <item name="android:windowFrame">@null</item>        <item name="android:windowNoTitle">true</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowIsTranslucent">true</item>        <item name="android:windowAnimationStyle">@style/dialog_animation</item>        <item name="android:backgroundDimEnabled">true</item>        <item name="android:windowBackground">@android:color/transparent</item>    </style>    <style name="dialog_animation" parent="@android:style/Animation.Dialog">        <item name="android:windowEnterAnimation">@anim/push_bottom_in</item>        <item name="android:windowExitAnimation">@anim/push_bottom_out</item>    </style>

两个动画文件：
push_bottom_in.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <translate        android:duration="400"        android:fromYDelta="100%p"        android:toYDelta="0" />    <alpha        android:duration="400"        android:fromAlpha="0.0"        android:toAlpha="1.0" /></set>

push_bottom_out.xml

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android" >    <translate        android:duration="400"        android:fromYDelta="0"        android:toYDelta="50%p" />    <alpha        android:duration="400"        android:fromAlpha="1.0"        android:toAlpha="0.0" /></set>
