关于Button点击弹出输入框，并且通过Servlet连接数据库

　应主管的要求，做了一个月的Android，对Android也发生了许多的问题，下面是主管让我弄的一个弹出输入框，能够输入评论，保存到数据库的功能
　　这是MainActivity类中的内容
// 评论按钮
comment = (Button) findViewById(R.id.comment);
comment.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// LayoutInflater inflater = getLayoutInflater();
// final View layout = inflater.inflate(R.layout.comment,(ViewGroup) findViewById(R.id.dialog));
// 获取文本
final EditText inputServer = new EditText(MainActivity.this);
// 设置获取文本内容为true
inputServer.setFocusable(true);
if(MainActivity.CityName == null){
inputServer.setText("你还未搜索当前城市，请定位后再评论");
}
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("评价框").setView(inputServer);
builder.setNegativeButton("取消", null);
builder.setPositiveButton("确定", new DialogInterface.OnClickListener(){
@Override
public void onClick(DialogInterface arg0, int arg1) {
String text = inputServer.getText().toString();
if(MainActivity.CityName == null){
HttpGet httpGet = new HttpGet("http://192.168.11.135:8081/MySql/pinlunServlet?cityName=null&comment=" + text);
try {
HttpResponse response = new DefaultHttpClient().execute(httpGet);
if(response.getStatusLine().getStatusCode() < 2000){
Log.i("add", "评论成功");
}else{
Log.e("Err", "评论失败");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}else{
HttpGet httpGet = new HttpGet("http://192.168.11.135:8081/MySql/pinlunServlet?cityName=" + MainActivity.CityName + "&comment=" + text);
try {
HttpResponse response = new DefaultHttpClient().execute(httpGet);
if(response.getStatusLine().getStatusCode() < 2000){
Log.i("add", "评论成功");
}else{
Log.e("Err", "评论失败");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Log.i("add",text);
}});
builder.show();
}
});

　这是comment.xml中的配置
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content" android:layout_width="wrap_content"
android:background="#ffffffff" android:orientation="horizontal"
android:id="@+id/dialog">
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="@+id/tvname"
android:text="评论：" />
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="@+id/etname"
android:minWidth="100dip"/>
</LinearLayout>
AndroidManifest.xml中权限(仅供参考，如有缺少可以添加)
<?xml version="1.0" encoding="utf-8"?>
