Android获取应用程序名称(ApplicationName)

MainActivity如下:

[java]
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;

    @Override
    protected 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;
    }

}

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;

@Override
protected 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:

[html]
<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>

</RelativeLayout>
