android：控件自定义-对话框

1. 在values的styles.xml中定义对话框样式：

< style name = "HorizonDialog" parent = "@android:Theme.Dialog" >

        < item name = "android:windowFrame" > @null </ item >

        < item name = "android:windowNoTitle" > true </ item >

        < item name = "android:windowIsFloating" > true </ item >

        < item name = "android:windowContentOverlay" > @null </ item >

</ style >

2. 自定义对话框布局

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

< LinearLayout xmlns:android = " http://schemas.android.com/apk/res/android" ;

    android:layout_width = "256dip"

    android:layout_height = "wrap_content"

    android:orientation = "vertical"

    android:layout_gravity = "center"

    android:background = "#BFBFBF" >

   

    < LinearLayout

        android:layout_width = "fill_parent"

        android:layout_height = "50dip"

        android:gravity = "center"

        android:orientation = "vertical"

        android:background = "#FFFFFF"

        android:layout_marginBottom = "1dip" >

       

       < TextView

          android:layout_width = "wrap_content"

          android:layout_height = "wrap_content"

          android:textColor = "#000000"

          android:textSize = "22sp"

          android:text = " 登录" />

      

    </ LinearLayout >

   

    < LinearLayout

        android:layout_width = "fill_parent"

        android:layout_height = "wrap_content"

        android:paddingTop = "15dip"

        android:paddingBottom = "15dip"

        android:background = "#FFFFFF"

        android:layout_marginBottom = "1dip"

        android:gravity = "center"

        android:orientation = "vertical" >

      

       < EditText

          android:id = "@+id/et_paw"

          android:layout_width = "216dip"

          android:layout_height = "wrap_content"

          android:scrollHorizontally = "true"  

          android:hint = " 密码"

          android:inputType = "textPassword" />

      

    </ LinearLayout >

    < LinearLayout

        android:layout_width = "fill_parent"

        android:layout_height = "wrap_content"

        android:orientation = "horizontal" >

        < Button

            android:id = "@+id/btn_ok"

            android:layout_width = "match_parent"

            android:layout_height = "40dip"

            android:layout_weight = "1"

            android:layout_marginRight = "1dip"

            android:text = " 确定"

            android:background = "#FFFFFF" />

        < Button

            android:id = "@+id/btn_cancel"

            android:layout_width = "match_parent"

            android:layout_height = "40dip"

            android:layout_weight = "1"

            android:text = " 取消"

            android:background = "#FFFFFF" />

    </ LinearLayout >

</ LinearLayout >

3. 代码

final Dialog loginDialog = new Dialog( context , R.style. HorizonDialog ) ;

loginDialog. setContentView ( R.layout. dialog_login );

final EditText et_paw = (EditText)loginDialog.findViewById(R.id. et_paw );

Button btn_ok = (Button)loginDialog.findViewById(R.id. btn_ok );

Button btn_cancel = (Button)loginDialog.findViewById(R.id. btn_cancel );

btn_ok.setOnClickListener( new OnClickListener() {

@Override

public void onClick(View v) {

    。。。。

}

});

btn_cancel.setOnClickListener( new OnClickListener() {

    @Override

    public void onClick(View v) {
