CSDN簡單安卓用戶端實現，csdn安卓用戶端

一直是在電腦上面看CSDN的部落格、資訊，今天做了個小軟體在手機上面查看資訊和部落格。

                    

直接上代碼：

一、首先是歡迎介面 --  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);}}

其布局檔案很簡單--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>

二、首頁面--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.os.Bundle;import android.view.KeyEvent;import android.view.Menu;import android.view.MenuItem;import android.view.Window;import android.webkit.WebSettings.RenderPriority;import android.webkit.WebView;import android.webkit.WebViewClient;import android.widget.Toast;public class ShowActivity extends Activity {private WebView webView;private static Boolean isExit = false;Timer tExit = new Timer();// 計時器TimerTask task;@SuppressLint("SetJavaScriptEnabled")@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.activity_main);webView = (WebView) findViewById(R.id.web_view);webView.getSettings().setBuiltInZoomControls(true);webView.getSettings().setJavaScriptEnabled(true);webView.getSettings().setRenderPriority(RenderPriority.HIGH);// webView.getSettings().setBlockNetworkImage(true);webView.setWebViewClient(new WebViewClient() {@Overridepublic boolean shouldOverrideUrlLoading(WebView view, String url) {// 根據傳入的參數再去載入新的網頁view.loadUrl(url);// 表示當前WebView可以處理開啟新網頁的請求，不用藉助系統瀏覽器return true;}@Overridepublic void onReceivedError(WebView view, int errorCode,String description, String failingUrl) {super.onReceivedError(view, errorCode, description, failingUrl);Toast.makeText(ShowActivity.this, "呃！載入失敗，也許斷網了，或者不能訪問！",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();// 返回前一個頁面return true;}return super.onKeyDown(keyCode, event);}@Overridepublic void onBackPressed() {if (isExit == false) {isExit = true;Toast.makeText(this, "再按一次返回鍵回到案頭", 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);// 添加四個功能表項目menu.add(Menu.NONE, Menu.FIRST + 1, 1, "協助").setIcon(R.drawable.menu_help);menu.add(Menu.NONE, Menu.FIRST + 2, 2, "退出").setIcon(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("退出").setMessage("你確定要退出CSDN嗎？").setIcon(android.R.drawable.ic_dialog_info).setPositiveButton(R.string.ok,new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog,int whichButton) {finish();// 退出程式}}).setNegativeButton(R.string.cancel, null).show();return true;}return false;}}

布局檔案--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>

三、協助頁面--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);}}

布局檔案--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="0,1,2" >    <TableRow>        <TextView            android:layout_width="100dp"            android:layout_height="match_parent"            android:layout_marginRight="10dp"            android:text="第一步："            android:textSize="23sp" />        <TextView            android:layout_width="100dp"            android:layout_height="match_parent"            android:layout_marginRight="5dp"            android:layout_marginLeft="5dp"            android:text="第二步："            android:textSize="23sp" />        <TextView            android:layout_width="100dp"            android:layout_height="match_parent"            android:layout_marginRight="10dp"            android:text="第三步："            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="右上方表徵圖"            android:textSize="15sp" />        <TextView            android:layout_width="100dp"            android:layout_height="match_parent"            android:layout_marginRight="5dp"            android:layout_marginLeft="5dp"            android:text="點擊部落格"            android:textSize="15sp" />        <TextView            android:layout_width="100dp"            android:layout_height="match_parent"            android:layout_marginRight="10dp"            android:text="點擊登入"            android:textSize="15sp" />    </TableRow>    <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>

四、最後別忘了在AndroidManifest.xml檔案中添加訪問網路的許可權

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