实现定制的dialog

经常用UC，它的dialog就是定制的。对它进行了模仿。

对这个dialog，我用gridview来实现的，所以另外启动了一个activity。

也可以继承dialog，那样的话，界面好像要在布局文件中写死？

主界面的布局：

<?xml version="1.0" encoding="utf-8"?>
<GridView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_gravity="center_vertical|center_horizontal"
  android:horizontalSpacing="5dp"  
  android:verticalSpacing="20dp"
  android:id="@+id/gridview"
  android:numColumns="auto_fit"
  android:stretchMode="columnWidth"
  android:columnWidth="80dp"
  android:padding="5dp"
  android:listSelector="@drawable/grid_item_selector"
  >
</GridView>

每一项的布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:orientation="vertical"
  android:padding="5dp">
  <ImageView
  	android:layout_width="wrap_content"
  	android:layout_height="wrap_content"
  	android:layout_marginBottom="2dp"
  	android:scaleType="center"
  	android:layout_gravity="center_horizontal"
  	android:id="@+id/dialog_image"
	/>
	<TextView
		android:layout_width="wrap_content"	
		android:layout_height="wrap_content"
		android:id="@+id/ialog_text"
		android:singleLine="true"
		/>
</LinearLayout>

再就是这个activity的代码了。

public class DialogActivity extends Activity {
	List<HashMap<String, Object>> datas = null;
	String[] dialog_text = {
		"新建窗口","加入书签","页面属性","自由赋值","分享页面"	
	};
	
	int[] dialog_img = {
		android.R.drawable.ic_dialog_info,
		android.R.drawable.ic_dialog_email,
		android.R.drawable.ic_dialog_info,
		android.R.drawable.ic_dialog_map,
		android.R.drawable.ic_dialog_alert,
	};
	
	View view;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        
        setContentView(R.layout.dialog);
        
        
        initResources();
		SimpleAdapter adapter = new SimpleAdapter(this, datas, R.layout.dialog_item, 
        		new String[]{"text","image"}, 
        		new int[]{R.id.ialog_text, R.id.dialog_image});
        GridView grid = (GridView) findViewById(R.id.gridview);
        grid.setAdapter(adapter);
        
        grid.setOnItemClickListener(new OnItemClickListener() {
			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				Toast.makeText(DialogActivity.this, "" + position, 1000).show();
			}
		});
    }
    
    private void initResources() {
		datas  = new ArrayList<HashMap<String,Object>>();
		for(int i=0; i<dialog_text.length; i++) {
			HashMap<String,Object> map = new HashMap<String, Object>(dialog_text.length);
			map.put("text", dialog_text[i]);
			map.put("image", dialog_img[i]);
			datas.add(map);
		}
	}
}

在清单文件上，对这个activity进行主题设置

android:theme="@style/Dialog_NoTitle_Translucte">

自定义主题

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Dialog_NoTitle_Translucte" parent="@android:style/Theme.Dialog">
         <item name="android:windowNoTitle">true</item>
       <!-- 透明
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:colorBackgroundCacheHint">@null</item>
        <item name="android:windowIsTranslucent">true</item>
        
         -->
        <item name="android:backgroundDimEnabled">false</item><!--activity不变暗-->
    </style>
</resources>
