Android Realization Youdao Thesaurus Query Function example detailed _android

This article is an example of Android to achieve Youdao Dictionary query function method. Share to everyone for your reference, specific as follows:

This is what I do a simple Youdao Android demo, just a simple prototype. The interface design is also a bit ugly oh ~ look at the following effect chart:

The first step: the analysis of Ideas

A total of three control Edittext,button,webview are used from the interface. It's actually four, which is the toast control we use to prompt when our query content is empty.

We enter the inquiry content in EditText, here includes Chinese, English. And then, by the form of the parameter, the data is removed from the http://dict.youdao.com/m
stored in the WebView.

As shown in the following illustration:

Step Two: Start program

First is the layout interface Main.xml

<?xml version= "1.0" encoding= "Utf-8"?> <absolutelayout xmlns:android= "http://schemas.android.com/apk/res/"
 Android "android:orientation=" vertical "android:layout_width=" fill_parent "android:layout_height=" Fill_parent " > <!--establish a edittext--> <edittext android:id= "@+id/myedittext1" android:layout_width= "200px" Android:layo ut_height= "40px" android:textsize= "18sp" android:layout_x= "5px" android:layout_y= "32px"/> <!--set up a button--&G
 T
 <button android:id= "@+id/mybutton01" android:layout_width= "60px" android:layout_height= "40px" android:text= "Query" android:layout_x= "205px" android:layout_y= "35px"/> <button android:id= "@+id/mybutton02" Android:layout_heigh t= "40px" android:layout_width= "50px" android:text= "Empty" android:layout_y= "35px" android:layout_x= "270px"/> &L t;! --Establish a webview--> <webview android:id= "@+id/mywebview1" android:layout_height= "330px" android:layout_width= " 300px "android:layout_x=" 7px "AndrOid:layout_y= "90px" android:background= "@drawable/black" android:focusable= "false"/> </AbsoluteLayout> 

followed by main class Youdao.java

Package androidapplication.instance;
Import android.app.Activity;
Import Android.os.Bundle;
Import Android.view.View;
Import Android.webkit.WebView;
Import Android.widget.Button;
Import Android.widget.EditText;
Import Android.widget.Toast;
 public class Youdao extends activity {//Query button affirms private button myButton01;
 Empty button to declare private button myButton02;
 The input box declares private edittext mEditText1;
 Load data WebView stated that private WebView mWebView1;
  public void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
  Setcontentview (R.layout.main);
  Get the layout of several controls MyButton01 = (Button) Findviewbyid (R.ID.MYBUTTON01);
  MYBUTTON02 = (Button) Findviewbyid (R.ID.MYBUTTON02);
  MEditText1 = (edittext) Findviewbyid (R.ID.MYEDITTEXT1);
  MWebView1 = (webview) Findviewbyid (R.ID.MYWEBVIEW1); Query button Add Event Mybutton01.setonclicklistener (new Button.onclicklistener () {public void OnClick (View arg0) {S
     Tring Struri = (Medittext1.gettext (). toString ()); Struri = Struri.trim ();
        If the query content is null prompt if (struri.length () = = 0) {toast.maketext (youdao.this, "query content cannot be empty!", Toast.length_long)
     . Show ();
     //Otherwise obtain data from http://dict.youdao.com/m in the form of parameters and load into WebView.
      else {String strURL = "http://dict.youdao.com/m/search?keyfrom=dict.mindex&q=" + Struri;
     Mwebview1.loadurl (strURL);
  }
    }
  });
   The empty button adds an event, edittext the Empty Mybutton02.setonclicklistener (new Button.onclicklistener () {public void OnClick (View v)
   {Medittext1.settext ("");
 }
  });

 }
}

The program is done. In fact, we will find that the application is quite simple, but you did not think of it, narcissism ah ~.
