CSDN is implemented by simple Android clients and csdn Android clients

I have been reading CSDN blogs and information on my computer. Today I have made a small software program to view information and blogs on my mobile phone.

Directly run the Code:

I. Welcome interface-LoadingActivity. java

package com.example.webviewtest;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.os.Handler;import android.view.Window;public class LoadingActivity extends Activity{@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.loading);new Handler().postDelayed(new Runnable() {@Overridepublic void run() {Intent mainIntent = new Intent(LoadingActivity.this,ShowActivity.class);startActivity(mainIntent);finish();}}, 2000);}}

The layout file is simple-loading. xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <ImageView        android:id="@+id/imageView"        android:layout_width="wrap_content"        android:layout_height="fill_parent"        android:src="@drawable/splash" /></LinearLayout>

2. Home Page -- ShowActivity. java

Package com. example. webviewtest; import java. util. timer; import java. util. timerTask; import android. annotation. suppressLint; import android. app. activity; import android. app. alertDialog; import android. content. dialogInterface; import android. content. intent; import android.

You do not need to use the system browser to return true;} @ Overridepublic void onReceivedError (WebView view, int errorCode, String description, string failingUrl) {super. onReceivedError (view, errorCode, description, failingUrl); Toast. makeText (ShowActivity. this, "er! Loading failed. The network may be disconnected or cannot be accessed! ", Toast. LENGTH_LONG ). show () ;}}); webView. loadUrl ("http://www.csdn.net/") ;}@ Overridepublic boolean onKeyDown (int keyCode, KeyEvent event) {if (keyCode = KeyEvent. KEYCODE_BACK & webView. canGoBack () {webView. goBack (); // return the previous page return true;} return super. onKeyDown (keyCode, event) ;}@ Overridepublic void onBackPressed () {if (isExit = false) {isExit = true; Toast. makeText (this, "press the return key again to return to the desktop", Toast. LENGTH _ SHORT ). show (); task = new TimerTask () {@ Overridepublic void run () {isExit = false ;}}; tExit. schedule (task, 2000);} else {finish (); System. exit (0) ;}@ Overridepublic boolean onCreateOptionsMenu (Menu menu) {// TODO Auto-generated method stubsuper. onCreateOptionsMenu (menu); // Add four menu items. add (Menu. NONE, Menu. FIRST + 1, 1, "help "). setIcon (R. drawable. menu_help); menu. add (Menu. NONE, Menu. FIRST + 2, 2, "quit "). se TIcon (R. drawable. menu_quit); return true ;}@ Overridepublic boolean onOptionsItemSelected (MenuItem item) {// TODO Auto-generated method stubswitch (item. getItemId () {case Menu. FIRST + 1: Intent intent = new Intent (ShowActivity. this, HelpActivity. class); startActivity (intent); return true; case Menu. FIRST + 2: new AlertDialog. builder (this ). setTitle ("quit "). setMessage ("are you sure you want to exit CSDN? "). SetIcon (android. r. drawable. ic_dialog_info ). setPositiveButton (R. string. OK, new DialogInterface. onClickListener () {public void onClick (DialogInterface Diener, int whichButton) {finish (); // exit program }}). setNegativeButton (R. string. cancel, null ). show (); return true;} return false ;}}

Layout file -- activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <WebView        android:id="@+id/web_view"        android:layout_width="match_parent"        android:layout_height="match_parent" /></LinearLayout>

3. Help page -- HelpActivity. java

package com.example.webviewtest;import android.app.Activity;import android.os.Bundle;import android.view.Window;public class HelpActivity extends Activity{@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.help);}}

Layout file -- help. xml

<? Xml version = "1.0" encoding = "UTF-8"?> <TableLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: stretchColumns = ", 2"> <TableRow> <TextView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "10dp" android: text = "Step 1:" android: textSize = "23sp"/> <TextView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "5dp" android: layout_marginLeft = "5dp" android: text = "Step 2:" android: textSize = "23sp"/> <TextView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "10dp" android: text = "Step 3:" android: textSize = "23sp"/> </TableRow> <TableRow android: layout_marginTop = "20dp"> <TextView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "10dp" android: text = "icon in the upper right corner" android: textSize = "15sp"/> <TextView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "5dp" android: layout_marginLeft = "5dp" android: text = "Click blog" android: textSize = "15sp"/> <TextView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "10dp" android: text = "click to log on" android: textSize = "15sp"/> </TableRow> <ImageView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginRight = "10dp" android: src = "@ drawable/first"/> <ImageView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginLeft = "5dp" android: layout_marginRight = "5dp" android: src = "@ drawable/second"/> <ImageView android: layout_width = "100dp" android: layout_height = "match_parent" android: layout_marginLeft = "10dp" android: src = "@ drawable/third"/> </TableRow> </TableLayout>

4. Do not forget to add the network access permission to the AndroidManifest. xml file.

 <uses-permission android:name="android.permission.INTERNET" />
