Android Implementation of Youdao Dictionary Query Function Example in Detail

This article describes the method of implementing the Youdao Dictionary query function in Android. Share it with everyone for reference, as follows:

This is a simple YouDao Android DEMO I made, just a simple prototype. The interface design is a bit ugly,呵呵~ Take a look at the following effect picture:

First step: Idea analysis

From the interface, it seems that three controls EditText, Button, WebView are used in total. In fact, there are four, which is a Toast control used to prompt when the query content is empty.

We input the query content in EditText, which includes Chinese and English. Then, in the form of parameters, fromhttp://dict.youdao.com/mExtract the data and output the result
Stored in WebView.

As shown in the figure below:

Second step: Start the program

The first step is to establish 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 an EditText -->
 <EditText
 android:id="@"+id/myEditText1"
 android:layout_width="200px"
 android:layout_height="40px"
 android:textSize="18sp
 android:layout_x="5px"
 android:layout_y="32px"
 />
 <!-- Establish a Button -->
 <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_height="40px"
  android:layout_width="50px"
  android:text="Clear"
  android:layout_y="35px"
  android:layout_x="270px"
 />
 <!-- 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>

The main class is 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
{
 //Declaration of query button
 private Button myButton01;
 //Declaration of clear button
 private Button myButton02;
 //Declaration of input box
 private EditText mEditText1;
 //Declaration of WebView to load data
 private WebView mWebView1;
 public void onCreate(Bundle savedInstanceState)
 {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);
  //Obtain several controls of the layout
  myButton01 = (Button) findViewById(R.id.myButton01);
  myButton02 = (Button) findViewById(R.id.myButton02);
  mEditText1 = (EditText) findViewById(R.id.myEditText1);
  mWebView1 = (WebView) findViewById(R.id.myWebView1);
  //Add an event to the query button
  myButton01.setOnClickListener(new Button.OnClickListener())
  {
   public void onClick(View arg0)
    {
     String strURI = (mEditText1.getText().toString());
     strURI = strURI.trim();
     //If the query content is empty, prompt
     if (strURI.length() == 0)
     {
      Toast.makeText(YouDao.this, "The query content cannot be empty!", Toast.LENGTH_LONG)
        .show();
     }
     //Otherwise, obtain it in the form of parameters from http:\://dict.youdao.com/m gets data, loads it into WebView.
     else
     {
      String strURL = "http:\"://dict.youdao.com/m/search?keyfrom=dict.mindex&q="
        + strURI;
      mWebView1.loadUrl(strURL);
     }
    }
  });
  //Add event to clear button, set EditText to empty
  myButton02.setOnClickListener(new Button.OnClickListener())
  {
   public void onClick(View v)
   {
    mEditText1.setText("");
   }
  });
 }
}

The program is successfully completed. In fact, you will find that this application is quite simple, just that you didn't think of it, Narcissism, haha~.
