窗口的XML文件：

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/my_wifi_password_TableLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">


<TableRow
android:id="@+id/my_wifi_password_TableRow1"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<LinearLayout
android:orientation="horizontal"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_weight="1">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="密码："
style="@style/my_socket_tcp_text_style">

</TextView>

<EditText
android:id="@+id/my_wifi_password_EditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="left"
android:singleLine="true"
android:textColor="#8B0000"
android:inputType="text"
android:text="">
</EditText>
</LinearLayout>

</TableRow>



</TableLayout>

在listview的监听事件中：

my_listview.setOnItemClickListener(new AdapterView.OnItemClickListener(){

@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
// TODO Auto-generated method stub
HashMap<String, String> my_map = (HashMap<String, String>) my_listview.getItemAtPosition(arg2);
String title = my_map.get("title");
String content = my_map.get("itemContent");

if(title.equals("扫描网络")){
handler.postDelayed(RefreshWifiList, 20);
return;
}

MySocketActivity.this.user_select_wifiname=title;
LayoutInflater inflater=getLayoutInflater();
View layout=inflater.inflate(R.layout.my_wifi_password,
(ViewGroup)findViewById(R.id.my_wifi_password_TableLayout));
MySocketActivity.this.passWord_EditText = (EditText)layout.findViewById(R.id.my_wifi_password_EditText);
AlertDialog my_DialogPassWord = new AlertDialog.Builder(MySocketActivity.this).create();
my_DialogPassWord.setTitle("请输入密码");
my_DialogPassWord.setView(layout);

my_DialogPassWord.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Toast.makeText(MySocketActivity.this,"选择了取消按钮",Toast.LENGTH_SHORT).show();
}
});
my_DialogPassWord.setButton(DialogInterface.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {

/*Toast.makeText(MySocketActivity.this,user_select_wifipassword,Toast.LENGTH_SHORT).show();*/
if(null != passWord_EditText) {
MySocketActivity.this. user_select_wifipassword=passWord_EditText.getText().toString();
if(user_select_wifipassword.equals("")){
MySocketActivity.this.user_select_wifipassword="null";
}
// if(!my_wificlass.isWiFiActive(MySocketActivity.this)) {
if(my_timer_state == 0) {
Toast.makeText(MySocketActivity.this,"正在连接-->"+user_select_wifiname,Toast.LENGTH_SHORT).show();
handler.postDelayed(runnable, 20);
}
// }

}
}
});
my_DialogPassWord.show();
}

});

注意：

MySocketActivity.this.passWord_EditText = (EditText)layout.findViewById(R.id.my_wifi_password_EditText);

一定要在

LayoutInflater inflater=getLayoutInflater();
View layout=inflater.inflate(R.layout.my_wifi_password,
(ViewGroup)findViewById(R.id.my_wifi_password_TableLayout));

后面，否则passWord_EditText 为null

wifi类别刷新：

public void my_Refresh_wifi_list(){
my_list_wifi=my_wificlass.my_WifiList(MySocketActivity.this);
List<Map<String,Object>> my_list = new ArrayList<Map<String, Object>>();
for (int i=0;i<my_list_wifi.size();i++){
Map<String,Object> map=new HashMap<String,Object>();
if(Math.abs(my_list_wifi.get(i).level)>80){
map.put("image",my_imageld[1]);
}else if(Math.abs(my_list_wifi.get(i).level)>60){
map.put("image",my_imageld[2]);
}else if(Math.abs(my_list_wifi.get(i).level)>40){
map.put("image",my_imageld[3]);
}else {
map.put("image",my_imageld[4]);
}
map.put("title",my_list_wifi.get(i).SSID);

if(my_list_wifi.get(i).capabilities.contains("WPA")){
map.put("KwyType","WPA加密");
}else if(my_list_wifi.get(i).capabilities.contains("WEP")){
map.put("KwyType","WEP加密");
}else {
map.put("KwyType","无密码");
}

my_list.add(map);
}
//添加扫描按钮
Map<String,Object> map=new HashMap<String,Object>();
map.put("image",my_imageld[0]);
map.put("title","扫描网络");
map.put("KwyType","。。。。。。");
my_list.add(map);

SimpleAdapter adapter=new SimpleAdapter(MySocketActivity.this,my_list,R.layout.my_socket_wifi_list_items,
new String[]{"title","KwyType","image"},
new int[]{R.id.my_socket_wifi_list_items_WifiName,
R.id.my_socket_wifi_list_items_WifKeyType,
R.id.my_socket_wifi_list_items_ImageView});
my_listview.setAdapter(adapter);
}
