Android 自定义对话框

先看效果：

 

         

 

 

 

这是我做的一个拨号器强的面板，拨号的时候会查询手机中的联系人，显示在拨号面板上方，点击弹出透明对话框供选择。

 

这次重点是透明对话框。

 

先看对话框的theme，style文件：

 

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style
        name="selectorDialog"
        parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item><!--边框-->
        <item name="android:windowIsFloating">true</item><!--是否浮现在activity之上-->
        <item name="android:windowIsTranslucent">false</item><!--半透明-->
        <item name="android:windowNoTitle">true</item><!--无标题-->
        <item name="android:windowBackground">@drawable/selector_dialog_bg</item><!--背景透明-->
        <item name="android:backgroundDimEnabled">false</item><!--模糊-->
        <item name="android:backgroundDimAmount">0.6</item>
    </style>
</resources>

 

 

对话框背景@drawable/selector_dialog_bg：

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#333333"/>
    <stroke
        android:width="2dp"
        android:color="#99CC33" />
    <padding
        android:left="5dp"
        android:top="5dp"
        android:right="5dp"
        android:bottom="5dp" />
    <corners android:radius="8dp" />
</shape>

 

 

 

然后是对话框的布局：

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/selector_dialog_listview"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:cacheColorHint="#00000000"
        android:scrollbars="none"
        android:dividerHeight="1.0dip"
        android:divider="#C4C4C4" />

</LinearLayout>

程序中：

 

final View view = LayoutInflater.from(this).inflate(R.layout.selector_dialog, null);
        selectorDialog = new Dialog(DialerActivity.this, R.style.selectorDialog);
        selectorDialog.setContentView(view);

        final BaseAdapter adapter = new SelectorAdapter(DialerActivity.this, selectorList);
        ListView listView = (ListView) view.findViewById(R.id.selector_dialog_listview);
        listView.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //对话框中事件处理
            }

        });
        listView.setAdapter(adapter);
        selectorDialog.show();
        selectorDialog.setCanceledOnTouchOutside(true);

        WindowManager windowManager = getWindowManager();
        Display display = windowManager.getDefaultDisplay();
        WindowManager.LayoutParams lp = selectorDialog.getWindow().getAttributes();
        lp.width = (int)(display.getWidth() * 0.9);
        if(selectorList.size() > 7) {
            lp.height = (int)(display.getHeight() * 0.9);
        }
        lp.alpha = 0.8f;
        selectorDialog.getWindow().setAttributes(lp);

其实主要是通过WindowManager.LayoutParams给对话框设置属性。
