当按下主页按钮或屏幕关闭时,媒体播放器会停止音乐....即使活动失去焦点,我也希望音乐继续播放....但我希望音乐暂停以接听来电以及用户是否暂停音乐. ......当通过后退按钮关闭活动时,音乐应该停止

这是我的代码示例:

package com.example.acer.aartisangrah;

import android.content.Context;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.text.Html;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.SeekBar;
import android.widget.TextView;
import android.widget.Toast;

public class ekdanta extends AppCompatActivity implements Runnable, View.OnClickListener,SeekBar.OnSeekBarChangeListener {
TextView tv4;
Button b9, b10,but19;
int count = 0;
MediaPlayer play;
SeekBar seek_bar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_ekdanta);
    tv4 = (TextView) findViewById(R.id.textView9);
    tv4.setTextSize(18);
    tv4.setText(Html.fromHtml(getString(R.string.thirteen)));
    b9 = (Button) findViewById(R.id.b9);
    b10 = (Button) findViewById(R.id.b10);
    seek_bar = (SeekBar) findViewById(R.id.seekBar);
    seek_bar.setOnSeekBarChangeListener(this); …
