Android仿微信語(yǔ)音聊天界面設(shè)計(jì)
更新時(shí)間：2016年11月23日 17:13:54 作者：遲做總比不做強(qiáng)
這篇文章主要為大家詳細(xì)介紹了Android仿微信語(yǔ)音聊天界面設(shè)計(jì)代碼,具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下
有段時(shí)間沒(méi)有看視頻了，昨天晚上抽了點(diǎn)空時(shí)間，又看了下鴻洋大神的視頻教程，又抽時(shí)間寫(xiě)了個(gè)學(xué)習(xí)記錄。代碼和老師講的基本一樣，網(wǎng)上也有很多相同的博客。我只是在AndroidStudio環(huán)境下寫(xiě)的。
—-主界面代碼——
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);
//更新數(shù)據(jù)
mAdapter.notifyDataSetChanged();
//設(shè)置位置
mListView.setSelection(mDatas.size() - 1);
}
});
mAdapter = new RecoderAdapter(this, mDatas);
mListView.setAdapter(mAdapter);
//listView的item點(diǎn)擊事件
mListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {
// 聲音播放動(dòng)畫(huà)

public void onCompletion(MediaPlayer mp) {
