BindService的示例

通過方法bindService(Intent intent,ServiceConnection conn,int flags)開啟服務。

下面是一個示例：

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="OK"
        android:onClick="test"/>
</RelativeLayout>
           

MainActivity.java:

package com.miao.mybindservice;

import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.IBinder;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.i("miao","MainActivity onCreate ...");
    }

    public void test(View view) {
        Intent intent = new Intent("rmiService");
        bindService(intent, new ServiceConnection() {
            @Override
            public void onServiceConnected(ComponentName name, IBinder proxy) {
                RmiService.MyBindService mb = (RmiService.MyBindService)proxy;
                Log.i("miao",mb.getProgress() + "....................................");
            }

            @Override
            public void onServiceDisconnected(ComponentName name) {

            }
        }, BIND_AUTO_CREATE);
    }
}
           

RmiService.java:

package com.miao.mybindservice;

import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;

public class RmiService extends Service {
    private int progress = 100;

    public class MyBindService extends Binder {
        public int getProgress(){
            return progress;
        }
    }

    public RmiService() {
    }

    @Override
    public IBinder onBind(Intent intent){
        return new MyBindService();
    }
}
