在Android中,如何避免onStart方法被弃用?

我遇到了在我的应用程序中设置onStart方法的问题。 它总是有一个删除线,说:“这个方法已被弃用在API级别5.我需要onStart,而不是onStartCommand。

我该如何解决这个问题?

MyNotificationService.java

import android.app.Service; import android.content.Intent; import android.os.IBinder; import android.widget.Toast; public class MyNotificationService extends Service { @Override public IBinder onBind(Intent arg0) { // TODO Auto-generated method stub return null; } @Override public void onCreate() { // TODO Auto-generated method stub super.onCreate(); Toast.makeText(this, "OnCreate()", Toast.LENGTH_SHORT).show(); } @Override public void onDestroy() { // TODO Auto-generated method stub super.onDestroy(); Toast.makeText(this, "OnDestroy()", Toast.LENGTH_SHORT).show(); } @Override @Deprecated public void onStart(Intent intent, int startId) { // TODO Auto-generated method stub super.onStart(intent, startId); } } 

Reminder_2.java

 import android.media.MediaPlayer; import android.os.Bundle; import android.app.Activity; import android.content.Intent; import android.view.Menu; import android.view.View; import android.view.Window; import android.widget.DatePicker; import android.widget.ImageButton; public class Reminder_2 extends Activity { String message; DatePicker datepicker; @Override protected void onCreate(Bundle savedInstanceState) { requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); setContentView(R.layout.activity_reminder_2); datepicker=(DatePicker)findViewById(R.id.datePicker1); Home(); Next(); Save(); } private void Next() { final MediaPlayer button_tone = MediaPlayer.create(this, R.raw.button_sound); ImageButton Button = (ImageButton) findViewById(R.id.imageButton1); View.OnClickListener myListener = new View.OnClickListener() { @Override public void onClick(View v) { button_tone.start(); finish(); } }; Button.setOnClickListener(myListener); } private void Save() { final MediaPlayer button_tone = MediaPlayer.create(this, R.raw.button_sound); ImageButton Button = (ImageButton) findViewById(R.id.imageButton3); View.OnClickListener myListener = new View.OnClickListener() { @Override public void onClick(View v) { button_tone.start(); Intent intent = new Intent(); intent.setClass(getApplicationContext(), MyNotificationService.class); startService(intent); } }; Button.setOnClickListener(myListener); } private void Home() { final MediaPlayer button_tone = MediaPlayer.create(this, R.raw.button_sound); ImageButton Button = (ImageButton) findViewById(R.id.imageButton2); View.OnClickListener myListener = new View.OnClickListener() { @Override public void onClick(View v) { button_tone.start(); Intent intent = new Intent(getApplicationContext(), MainActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(intent); } }; Button.setOnClickListener(myListener); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.reminder, menu); return true; } }

使用onStartCommand()

你想知道更多关于他们如何改变它,参考下面的谷歌文档。

 // This is the old onStart method that will be called on the pre-2.0 // platform. On 2.0 or later we override onStartCommand() so this // method will not be called. @Override public void onStart(Intent intent, int startId) { handleStart(intent, startId); } @Override public int onStartCommand(Intent intent, int flags, int startId) { handleStart(intent, startId); return START_NOT_STICKY; }
