MapActivity.java

公共类 MainActivity 扩展 FragmentActivity {弹出窗口密码；谷歌地图；@覆盖protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);设置内容视图(R.layout.main)；按钮按钮= (Button)findViewById(R.id.button);button.setOnClickListener(new OnClickListener() {@覆盖公共无效 onClick(查看 v){启动弹出窗口()；}});}私人无效initialPopupWindow(){尝试{//我们需要获取LayoutInflater的实例，使用这个activity的上下文LayoutInflater inflater = (LayoutInflater) MainActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);//从预定义的 XML 布局膨胀视图查看布局 = inflater.inflate(R.layout.popupstellodetailpage,(ViewGroup) findViewById(R.id.popuplayout));//创建一个 300px 宽和 470px 高的 PopupWindowpw = new PopupWindow(布局, 300, 470, true);//在中间显示弹窗pw.showAtLocation(布局, Gravity.CENTER, 0, 0);地图=((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.popupmapview)).getMap();按钮 buttoncancel=(Button)layout.findViewById(R.id.buttoncancel);buttoncancel.setOnClickListener(new OnClickListener(){@覆盖public void onClick(查看 v){pw.dismiss();}});}捕获(异常 e){e.printStackTrace();}}}

解决方案

他们只是我发现的两个愚蠢的问题..你只需改变这个片段

 <片段android:id="@+id/popupmapview"android:layout_width="fill_parent"android:layout_height="fill_parent"android:layout_margin="10dp"class="com.google.android.gms.maps.SupportMapFragment"/>

到这个..

 <片段android:id="@+id/popupmapview"android:layout_width="fill_parent"android:layout_height="fill_parent"android:layout_margin="10dp"class="com.google.android.gms.maps.MapFragment"/>

并在方法 [initiatePopupWindow] 中更改一行

map= ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.popupmapview)).getMap();

到这个..

map = ((MapFragment) getFragmentManager().findFragmentById(R.id.popupmapview)).getMap();

i want to open the popup window on that i used the map v2 for displaying map v2 in popup window but is not display here i put my xml layout and activity class

main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginTop="100dp"
        android:text="Button" />

</RelativeLayout>

popupstellodetailpage.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/popuplayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/black"
    android:orientation="vertical" >

        <Button
            android:id="@+id/buttoncancel"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Cancel"
            android:layout_gravity="right"
             />

          <fragment
                    android:id="@+id/popupmapview"
                    android:layout_width="fill_parent"
                    android:layout_height="fill_parent"
                    android:layout_margin="10dp"
                    class="com.google.android.gms.maps.SupportMapFragment" />



</LinearLayout>

MapActivity.java

public class MainActivity extends  FragmentActivity {


     PopupWindow pw;
     GoogleMap map;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button button= (Button)findViewById(R.id.button);
        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                initiatePopupWindow();
            }
        });

    }


    private void initiatePopupWindow() 
    {
        try 
        {

            //We need to get the instance of the LayoutInflater, use the context of this activity
            LayoutInflater inflater = (LayoutInflater) MainActivity.this
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            //Inflate the view from a predefined XML layout
            View layout = inflater.inflate(R.layout.popupstellodetailpage,
                    (ViewGroup) findViewById(R.id.popuplayout));

            // create a 300px width and 470px height PopupWindow
            pw = new PopupWindow(layout, 300, 470, true);

            // display the popup in the center
            pw.showAtLocation(layout, Gravity.CENTER, 0, 0);


            map= ((SupportMapFragment) getSupportFragmentManager()
                     .findFragmentById(R.id.popupmapview)).getMap(); 


            Button buttoncancel=(Button)layout.findViewById(R.id.buttoncancel);
            buttoncancel.setOnClickListener(new OnClickListener() 
            {   
                @Override
                public void onClick(View v) 
                {
                     pw.dismiss();
                }

            });

        }
        catch (Exception e) 
        {
            e.printStackTrace();
        }


    }
}

解决方案

their is only two silly problem as I found .. You just change this fragment

                <fragment
                android:id="@+id/popupmapview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_margin="10dp"
                class="com.google.android.gms.maps.SupportMapFragment" />

to this..

                <fragment
                android:id="@+id/popupmapview"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:layout_margin="10dp"
                class="com.google.android.gms.maps.MapFragment" />

and change a line in method [initiatePopupWindow]

map= ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.popupmapview)).getMap(); 

to this..

map = ((MapFragment) getFragmentManager().findFragmentById(R.id.popupmapview)).getMap();
