     注意事項:

               配置檔案,強烈建議,要寫成私有模式
              SharedPreferences sharedPreferences = getSharedPreferences(name,MODE_PRIVATE);

Java程式碼詳見如下:(這裡加入了一個上下文選單的效果)

public class MainActivity extends AppCompatActivity {
   private TextView textView;

        public void handleMessage(android.os.Message msg) {
            if (msg.what == 0) {
                // 跟新文字內容
textView.setText(msg.arg1 + "");
} else if (msg.what == 1) {
                // 進行頁面跳轉
Intent intent = new Intent();
ComponentName componentName = new ComponentName(
                        MainActivity.
 
this, SecondActivity.class);
intent.setComponent(componentName);
startActivity(intent);
finish();
}
        }
    };
@Override
protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    }    //實現介面的寫法

} catch (InterruptedException e) {
                    // TODO Auto-generated catch block

}
            }
            // 告訴主執行緒,進行頁面跳轉Message message = new Message();

   }
