#一、Dialog布局文件
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
android:orientation="vertical"
android:padding="20.0dip" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#ff7200"
android:orientation="vertical" >
<TextView
android:id="@+id/title"
android:textColor="#ffffff"
android:textSize="20sp"
android:layout_width="fill_parent"
android:layout_height="50dp"
android:gravity="center"
android:text="自定义弹窗"
android:visibility="visible" />
<LinearLayout
android:id="@+id/content"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center" >
<TextView
android:background="#ffffff"
android:id="@+id/message"
android:textColor="#b8b8b8"
android:textSize="16sp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="left|center"
android:lineSpacingMultiplier="1.5"
android:paddingBottom="15.0dip"
android:paddingLeft="20.0dip"
android:paddingRight="20.0dip"
android:paddingTop="15.0dip" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="50dp"
android:layout_gravity="bottom"
android:background="#ffffff"
android:gravity="center"
android:orientation="horizontal" >
<TextView
android:layout_weight="1"
android:id="@+id/positiveTextView"
android:textColor="#b8b8b8"
android:textSize="16sp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="ok"
android:clickable="true"/>
<TextView
android:layout_weight="1"
android:id="@+id/negativeTextView"
android:textColor="#ff9138"
android:textSize="16sp"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="cancel"
android:clickable="true"/>
</LinearLayout>
</LinearLayout>
</FrameLayout>
#二、Style
<style name="Dialog" parent="android:style/Theme.Dialog">
<item name="android:background">#00000000</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">true</item>
</style>
#三、MainActivity代码
CustomDialog.Builder builder = new CustomDialog.Builder(MainActivity.this);
builder.setMessage("这个就是自定义的提示框");
builder.setTitle("提示");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int which)
dialog.dismiss();
//设置你的操作事项
Toast.makeText(MainActivity.this,"queding",Toast.LENGTH_SHORT).show();
);
builder.setNegativeButton("取消",
new android.content.DialogInterface.OnClickListener()
public void onClick(DialogInterface dialog, int which)
Toast.makeText(MainActivity.this,"queding",Toast.LENGTH_SHORT).show();
dialog.dismiss();
);
builder.create().show();

.addView(contentView, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.FILL_PARENT));
dialog.setContentView(layout);
