录音效果(类似微信)

按住按钮会显示一个正在录音的动态窗口，自动识别音量 效果图 大部分逻辑写在自定义组件RecordButton.java 和 AmrPlayBto.java xml简单引用即可

private AmrPlayBto mPlayButton;
private RecordButton mRecordButton;

mRecordButton.setOnFinishedRecordListener(new OnFinishedRecordListener() {
	@Override
	public void onFinishedRecord(String audioPath) {
		if (audioPath != null) {
			// Toast.makeText(context, "录音完成：" + audioPath,
			// Toast.LENGTH_SHORT).show();
			mPlayButton.setVisibility(View.VISIBLE);
			...
		} else {
			mPlayButton.setVisibility(View.GONE);
			...
		}
	}
});
