Answer 1

首先:MainActivity

protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}

public void dialogStyle(View v){
final Dialog d=new Dialog(this, R.style.dialog);
View vv = LayoutInflater.from(this).inflate(R.layout.dialog_test, null);
TextView delete = (TextView) vv.findViewById(R.id.delete);

d.setCanceledOnTouchOutside(true);
d.setContentView(vv);
d.show();

delete.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
d.dismiss();
}
});
}
}

然后：style

<style name="dialog" parent="@android:style/Theme.Dialog">
<item name="android:windowFrame">@null</item>
<item name="android:windowIsFloating">true</item>
<item name="android:windowIsTranslucent">false</item>
<item name="android:windowNoTitle">true</item>
<item name="android:background">@null</item>
<item name="android:backgroundDimEnabled">false</item>
<item name="android:windowBackground"> @android:color/transparent </item>
</style>

最后xml

<!--?xml version="1.0" encoding="utf-8"?-->

<relativelayout android:layout_width="fill_parent" android:layout_height="wrap_content">

<textview android:id="@+id/delete" android:layout_width="238dp" android:layout_height="58dp" android:background="#2c2c2c" android:text="删除联系人" android:textcolor="#ffffff" android:gravity="center" android:layout_centerhorizontal="true">
</textview></relativelayout>
</linearlayout>
