擷取Android手機型號,系統版本,App版本號碼等資訊

 MainActivity如下:

package cn.testgethandsetinfo;import android.os.Bundle;import android.text.TextUtils;import android.widget.TextView;import android.app.Activity;import android.content.Context;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;/** * Demo描述: * 獲得手機型號,系統版本,App版本號碼等資訊 */public class MainActivity extends Activity {    private TextView mTextView;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);init();}   private void init(){   mTextView=(TextView) findViewById(R.id.textView);   mTextView.setText(getHandSetInfo());   }  private String getHandSetInfo(){  String handSetInfo=  "手機型號:" + android.os.Build.MODEL +   ",SDK版本:" + android.os.Build.VERSION.SDK +   ",系統版本:" + android.os.Build.VERSION.RELEASE+  ",軟體版本:"+getAppVersionName(MainActivity.this);   return handSetInfo;  }  //擷取目前的版本號  private  String getAppVersionName(Context context) {String versionName = "";try {PackageManager packageManager = context.getPackageManager();PackageInfo packageInfo = packageManager.getPackageInfo("cn.testgethandsetinfo", 0);versionName = packageInfo.versionName;if (TextUtils.isEmpty(versionName)) {return "";}} catch (Exception e) {e.printStackTrace();}return versionName;}}

main.xml如下:
 

<RelativeLayout     xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    >    <TextView        android:id="@+id/textView"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world"         android:layout_centerInParent="true"        /></RelativeLayout>
