VoiceWaveView - An Android library that provides a voice wave effect.
For a working implementation of this project see the sample/ folder.
Include the library as local library project or add the dependency in your build.gradle.
dependencies {
compile 'me.kaneki.voicewaveview:library:0.0.4'
}Include the VoiceWaveView widget in your layout. And you can customize it like this. this view doesn't support wrap_content, Its size must be determined or match_parent.
<me.kaneki.voicewaveview.VoiceWaveView
android:id="@+id/voiceWaveView"
android:layout_width="300dp"
android:layout_height="40dp"
android:layout_centerHorizontal="true"
android:background="@drawable/msg_voice_panel_bg"
app:lineWidth="1.5dp"
app:dividerWidth="1dp"
app:duration="30"
app:refreshRatio="50"
app:backgroundColor="#7f7f7f"
app:activeLineColor="#ffffff"
app:inactiveLineColor="#99ffffff"/> If you want to record or play the recorded data, you can write these code, etc in your Activity.
VoiceWaveView mVoiceWaveView = (VoiceWaveView) findViewById(R.id.voiceWaveView);
//begin record
mVoiceWaveView.startRecord();
//set the record wave height percent (1-100), it can be used during other thread
mVoiceWaveView.setWaveHeightPercent(random.nextInt(100) + 1);
//stop record
mVoiceWaveView.stopRecord();
//get the last record data, you can change the waveData to json string or other type to save it
WaveData waveData = mVoiceWaveView.getLastWaveData();
//draw the give wave data as view
mVoiceWaveView.drawWaveData(waveData);
//start play, if the waveData is null, it will play the last record data
mVoiceWaveView.starPlay(waveData);
//pause the play or resume it
mVoiceWaveView.pauseOrResumePlay();WaveData contains last record wave list and duration, you can serialize it for local storage.
public class WaveData {
private ArrayList<WaveBean> waveList;
private long duration;
public WaveData(ArrayList<WaveBean> waveList, long duration) {
this.waveList = waveList;
this.duration = duration;
}
public ArrayList<WaveBean> getWaveList() {
return waveList;
}
public void setWaveList(ArrayList<WaveBean> waveList) {
this.waveList = waveList;
}
public long getDuration() {
return duration;
}
public void setDuration(long duration) {
this.duration = duration;
}
}| name | format | description |
|---|---|---|
| backgroundColor | color | background color, default is #7f7f7 |
| activeLineColor | color | active line color, default is #ffffff |
| inactiveLineColor | color | inactive line color, default is #99ffffff |
| lineWidth | dimension | wave line width, default is 1dp |
| dividerWidth | dimension | divider width between two wave line, default is 1dp |
| duration | integer | max record time , default is 30s |
| refreshRatio | integer | view refresh ratio, default is 50ms |
All attributes have their respective getters and setters to change them at runtime.
- add new public interface
drawWaveData. - extract the inner class
WaveDataandWaveBeanas public entity. - change the structure of internal code
VoiceWaveView
- removing personal configuration does not matter...
- fix get last wave data not contains duration.
- optimized wave data compression algorithm.
- library first build.
