安卓第三次作业
关键代码：
//启动服务器 Intent mintent=new Intent(); mintent.setClass(MainActivity.this, MyService.class); startService(mintent); zhuce(); list.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub isplay=true; playm.setImageResource(R.drawable.dainji_20); showgeci.setText("歌词"); Intent intent=new Intent(); intent.setAction("ACTION_INDEX"); intent.putExtra("index", arg2); sendBroadcast(intent); } }); // se.setOnSeekBarChangeListener(new OnSeekBarChangeListener() { @Override public void onStopTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } @Override public void onStartTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } @Override public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { // TODO Auto-generated method stub if(fromUser==true) { Intent intent=new Intent(); intent.setAction("ACTION_SEEKBAR"); intent.putExtra("seekbar", progress); sendBroadcast(intent); } } }); } @Override public void onClick(View v) { // TODO Auto-generated method stub switch (v.getId()) { case R.id.shang: nextmusic(0); lastm.setImageResource(R.drawable.dianji_22); break; case R.id.xia: nextmusic(1); nextm.setImageResource(R.drawable.dianji_25); break; case R.id.geci: isgeci=!isgeci; if(isgeci==true){ geci.setTextColor(Color.rgb(255, 255, 0)); showgeci.setVisibility(View.VISIBLE); }else{ geci.setTextColor(Color.rgb(255, 255, 255)); showgeci.setVisibility(View.GONE); } break; case R.id.line: check++; if(check>3) check=1; if(check==1){ style.setImageResource(R.drawable.dianji_28); stylemusic(1); } if(check==2){ style.setImageResource(R.drawable.dianji1_28); stylemusic(2); } if(check==3){ style.setImageResource(R.drawable.pic2_28); stylemusic(3); } break; case R.id.play: isplay=!isplay; if(isplay==true) { playm.setImageResource(R.drawable.dainji_20); }else{ playm.setImageResource(R.drawable.dianji_19); } musicplay(isplay); break; default: break; } } //发送，播放，暂停广播 public void musicplay(boolean isplay){ Intent intent=new Intent(); intent.setAction("ACTION_ISPLAY"); intent.putExtra("isplay",isplay); sendBroadcast(intent); } //上一曲，下一曲，0上一曲，1下一曲 public void nextmusic(int num){ showgeci.setText("歌词"); Intent intent=new Intent(); intent.setAction("ACTION_NEXT"); intent.putExtra("next",num); sendBroadcast(intent); } public void stylemusic(int num){ Intent intent=new Intent(); intent.setAction("ACTION_STYLE"); intent.putExtra("check",num); sendBroadcast(intent); } class Mybroad extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub if(intent.getAction().equals("ACTION_MAXTIME")){ int maxtime=intent.getIntExtra("maxtime", 0); se.setMax(maxtime); time2.setText(""+settime(maxtime)); } if(intent.getAction().equals("ACTION_NOWTIME")){ int nowtime=intent.getIntExtra("nowtime", 0); se.setProgress(nowtime); time.setText(""+settime(nowtime)); } if(intent.getAction().equals("ACTION_LRC")){ String lrc=intent.getStringExtra("geci"); showgeci.setText(""+lrc); } if(intent.getAction().equals("ACTION_NOWMUSIC")){ String nowmusic1=intent.getStringExtra("nowmusic"); nowmusic.setText("正在播放："+nowmusic1); } } }
