Android获取手机型号,系统版本,App版本号等信息

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:

 */

public class MainActivity extends Activity {

    private TextView mTextView;

	@Override

	protected 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=

	  "手机型号:" + android.os.Build.MODEL + 

	  ",SDK版本:" + android.os.Build.VERSION.SDK + 

	  ",系统版本:" + android.os.Build.VERSION.RELEASE+

	  ",软件版本:"+getAppVersionName(MainActivity.this); 

	  return handSetInfo;



  }

  //获取当前版本号

  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"
