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——

public class MainActivity extends Activity {

private ListView mListView;

private ArrayAdapter<Recorder> mAdapter;

private List<Recorder> mDatas = new ArrayList<Recorder>();

private AudioRecorderButton mAudioRecorderButton;

private View animView;

@Override

protected void onCreate(Bundle savedInstanceState) {

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(new AudioRecorderButton.AudioFinishRecorderCallBack() {

public void onFinish(float seconds, String filePath) {

Recorder recorder = new Recorder(seconds, filePath);

mDatas.add(recorder);

//更新数据

mAdapter.notifyDataSetChanged();

//设置位置

mListView.setSelection(mDatas.size() - 1);

}

});

mAdapter = new RecoderAdapter(this, mDatas);

mListView.setAdapter(mAdapter);

//listView的item点击事件

mListView.setOnItemClickListener(new OnItemClickListener() {

public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {

// 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);

AnimationDrawable animation = (AnimationDrawable) animView.getBackground();

animation.start();

// 播放录音

MediaPlayerManager.playSound(mDatas.get(position).filePath, new MediaPlayer.OnCompletionListener() {

public void onCompletion(MediaPlayer mp) {

//播放完成后修改图片

animView.setBackgroundResource(R.drawable.adj);

}

});

}

});

}

@Override

protected void onPause() {

super.onPause();

MediaPlayerManager.pause();

}

@Override

protected void onResume() {

super.onResume();

MediaPlayerManager.resume();

}

@Override

protected void onDestroy() {

super.onDestroy();

MediaPlayerManager.release();

}

代码中有注释,就不贴图了,和微信语音聊天界面一样的,所以叫仿微信嘛,呵呵。运行了也可以看到效果。所有代码可以从这里下载:http://xiazai.jb51.net/201611/yuanma/AndroidWXchat(jb51.net).rar
