MainActivity如下:

package cn.testapplicationname;import android.os.Bundle;import android.widget.TextView;import android.app.Activity;import android.content.pm.ApplicationInfo;import android.content.pm.PackageManager;/** * Demo描述: * 获取应用程序名称(ApplicationName) */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);String applicationName = getApplicationName();mTextView.setText("该应用名字:"+applicationName);}public String getApplicationName() {PackageManager packageManager = null;ApplicationInfo applicationInfo = null;try {packageManager = getApplicationContext().getPackageManager();applicationInfo = packageManager.getApplicationInfo(getPackageName(), 0);} catch (PackageManager.NameNotFoundException e) {applicationInfo = null;}String applicationName = (String) packageManager.getApplicationLabel(applicationInfo);return applicationName;}}

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>
