WaveLoadingView - An Android library that provides a realistic wave-loading effect.

For a working implementation of this project see the sample/ folder.

Include the library as a local library project or add the dependency in your build.gradle.

dependencies {
    implementation 'me.itangqi.waveloadingview:library:0.3.5'
    // I have uploaded v0.3.5 on 2017-01-06, if it doesn't take effect or your
    // gradle cannot find it in maven central, you may try v0.3.4.
}

Or

Import the library, then add it to your /settings.gradle and /app/build.gradle. If you don't know how to do this, you can read my blog for help.

Include the WaveLoadingView widget in your layout. And you can customize it like this.

<me.itangqi.waveloadingview.WaveLoadingView
    android:id="@+id/waveLoadingView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:wlv_borderColor="@color/colorAccent"
    app:wlv_borderWidth="3dp"
    app:wlv_progressValue="40"
    app:wlv_shapeType="circle"
    app:wlv_round_rectangle="true"
    app:wlv_triangle_direction="north"
    app:wlv_titleCenterStrokeColor="@android:color/holo_blue_dark"
    app:wlv_titleCenterStrokeWidth="3dp"
    app:wlv_titleCenter="Center Title"
    app:wlv_titleCenterColor="@android:color/white"
    app:wlv_titleCenterSize="24sp"
    app:wlv_waveAmplitude="70"
    app:wlv_waveColor="@color/colorAccent"/>   

You can write some animation codes to the callbacks such as setOnCheckedChangeListener, onProgressChanged, etc in your Activity.

    WaveLoadingView mWaveLoadingView = (WaveLoadingView) findViewById(R.id.waveLoadingView);
    mWaveLoadingView.setShapeType(WaveLoadingView.ShapeType.CIRCLE);
    mWaveLoadingView.setTopTitle("Top Title");
    mWaveLoadingView.setCenterTitleColor(Color.GRAY);
    mWaveLoadingView.setBottomTitleSize(18);
    mWaveLoadingView.setProgressValue(80);
    mWaveLoadingView.setBorderWidth(10);
    mWaveLoadingView.setAmplitudeRatio(60);
    mWaveLoadingView.setWaveColor(Color.GRAY);
    mWaveLoadingView.setBorderColor(Color.GRAY);
    mWaveLoadingView.setTopTitleStrokeColor(Color.BLUE);
    mWaveLoadingView.setTopTitleStrokeWidth(3);
    mWaveLoadingView.setAnimDuration(3000);
    mWaveLoadingView.pauseAnimation();
    mWaveLoadingView.resumeAnimation();
    mWaveLoadingView.cancelAnimation();
    mWaveLoadingView.startAnimation();
