自定义Dialog并去掉默认的头部

这东西很简单：

(1)我的Dialog布局history.xml：

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="" android:layout_width="fill_parent" android:layout_height="match_parent" android:layout_gravity="center_horizontal" android:orientation="vertical" android:background="#ffffff" >

<TextView android:layout_width="fill_parent" android:layout_height="32dp" android:background="@drawable/title" android:gravity="center" android:text="打开记录" android:textSize="20dp" android:textColor="#ffffff" > </TextView>

<GridView android:id="@+id/historypath" android:layout_width="280dp" android:layout_height="300dp" android:layout_gravity="center_horizontal" android:gravity="center" android:horizontalSpacing="20dp" android:verticalSpacing="20dp" android:numColumns="2" android:layout_marginTop="15dp" android:layout_marginLeft="15dp" android:layout_marginRight="15dp" > </GridView>

</LinearLayout>

history_item_content.xml：

<?xml version="1.0" encoding="utf-8"?> <ImageView xmlns:android="" android:id="@+id/img" android:layout_width="wrap_content" android:layout_height="wrap_content" android:descendantFocusability="blocksDescendants" android:focusable="false" />

(2)我的Dialog：

package com.zx.drawingborad;

import android.app.Dialog; import android.content.Context;

import android.graphics.Color; import android.os.Bundle; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.BaseAdapter; import android.widget.GridView; import android.widget.ImageView; import android.widget.AdapterView.OnItemClickListener;

public class BackGroupDialog extends Dialog implements OnItemClickListener { // private PaintView paintView; int drawble[] = { R.drawable.ditu };

public BackGroupDialog(Context context, int mydialogstyle) { super(context, mydialogstyle); // this.paintView = paintView; // TODO Auto-generated constructor stub }

@Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.history); GridView bgview = (GridView) findViewById(R.id.historypath); bgview.setAdapter(new DrawAdapter()); bgview.setOnItemClickListener(this);

}

class DrawAdapter extends BaseAdapter {

public DrawAdapter() { // TODO Auto-generated constructor stub

}

@Override public int getCount() { // TODO Auto-generated method stub

return drawble.length; }

@Override public Object getItem(int arg0) { // TODO Auto-generated method stub return null; }

@Override public long getItemId(int arg0) { // TODO Auto-generated method stub return 0; }

@Override public View getView(int arg0, View convertView, ViewGroup arg2) { // TODO Auto-generated method stub if (convertView == null) { convertView = (ImageView) getLayoutInflater().inflate( R.layout.history_item_content, null); } ((ImageView) convertView).setImageResource(drawble[arg0]); ((ImageView) convertView).setBackgroundColor(Color.YELLOW);

return convertView;

} }

@Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // TODO Auto-generated method stub this.dismiss(); } }

(3)在res-values-styles.xml中添加：

<style name="ShareDialog" parent="android:style/Theme.Dialog"> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowNoTitle">true</item><!-- 去掉头部 --> </style>

(4)在Activity中使用：

new BackGroupDialog(this,R.style.ShareDialog).show();
