Android仿微信语音聊天界面设计
有段时间没有看视频了，昨天晚上抽了点空时间，又看了下鸿洋大神的视频教程，又抽时间写了个学习记录。代码和老师讲的基本一样，网上也有很多相同的博客。我只是在AndroidStudio环境下写的。
—-主界面代码——
publicclassMainActivityextendsActivity{
privateListViewmListView;
privateArrayAdapter<Recorder>mAdapter;
privateList<Recorder>mDatas=newArrayList<Recorder>();
privateAudioRecorderButtonmAudioRecorderButton;
privateViewanimView;
@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mListView=(ListView)findViewById(R.id.id_listview);
mAudioRecorderButton=(AudioRecorderButton)findViewById(R.id.id_recorder_button);
mAudioRecorderButton.setFinishRecorderCallBack(newAudioRecorderButton.AudioFinishRecorderCallBack(){
publicvoidonFinish(floatseconds,StringfilePath){
Recorderrecorder=newRecorder(seconds,filePath);
mDatas.add(recorder);
//更新数据
mAdapter.notifyDataSetChanged();
//设置位置
mListView.setSelection(mDatas.size()-1);
}
});
mAdapter=newRecoderAdapter(this,mDatas);
mListView.setAdapter(mAdapter);
//listView的item点击事件
mListView.setOnItemClickListener(newOnItemClickListener(){
publicvoidonItemClick(AdapterView<?>arg0,Viewview,intposition,longid){
//声音播放动画
if(animView!=null){
animView.setBackgroundResource(R.drawable.adj);
animView=null;
}
animView=view.findViewById(R.id.id_recoder_anim);
animView.setBackgroundResource(R.drawable.play_anim);
AnimationDrawableanimation=(AnimationDrawable)animView.getBackground();
animation.start();
//播放录音
MediaPlayerManager.playSound(mDatas.get(position).filePath,newMediaPlayer.OnCompletionListener(){
publicvoidonCompletion(MediaPlayermp){
//播放完成后修改图片
animView.setBackgroundResource(R.drawable.adj);
}
});
}
});
}
@Override
protectedvoidonPause(){
super.onPause();
MediaPlayerManager.pause();
}
@Override
protectedvoidonResume(){
super.onResume();
MediaPlayerManager.resume();
}
@Override
protectedvoidonDestroy(){
super.onDestroy();
MediaPlayerManager.release();
}
