实战

1. 添加依赖

repositories 
    maven  url "https://jitpack.io" 

//...
dependencies 
    //...
    implementation 'com.github.elevenetc:textsurface:0.9.1'

2. 创建 TextSurface

<su.levenetc.android.textsurface.TextSurface
        android:id="@+id/text_surface"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

3. 使用 TextBuilder 创建存放文本的 Text 实例，并设置文字的样式参数：

public class CookieThumperSample 
    public static void play(TextSurface textSurface, AssetManager assetManager) 

        final Typeface robotoBlack = Typeface.createFromAsset(assetManager, "fonts/Roboto-Black.ttf");
        Paint paint = new Paint();
        paint.setAntiAlias(true);
        paint.setTypeface(robotoBlack);

        Text textDaai = TextBuilder
                .create("Daai")
                .setPaint(paint)
                .setSize(64)
                .setAlpha(0)
                .setColor(Color.WHITE)
                .setPosition(Align.SURFACE_CENTER).build();

        Text textBraAnies = TextBuilder
                .create("bra Anies")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.RED)
                .setPosition(Align.BOTTOM_OF, textDaai).build();

        Text textFokkenGamBra = TextBuilder
                .create(" hy's n fokken gam bra.")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.RED)
                .setPosition(Align.RIGHT_OF, textBraAnies).build();

        Text textHaai = TextBuilder
                .create("Haai!!")
                .setPaint(paint)
                .setSize(74)
                .setAlpha(0)
                .setColor(Color.RED)
                .setPosition(Align.BOTTOM_OF, textFokkenGamBra).build();

        Text textDaaiAnies = TextBuilder
                .create("Daai Anies")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.WHITE)
                .setPosition(Align.BOTTOM_OF | Align.CENTER_OF, textHaai).build();

        Text texThyLamInnie = TextBuilder
                .create(" hy lam innie mang ja.")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.WHITE)
                .setPosition(Align.RIGHT_OF, textDaaiAnies).build();

        Text textThrowDamn = TextBuilder
                .create("Throw damn")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.RED)
                .setPosition(Align.BOTTOM_OF | Align.CENTER_OF, texThyLamInnie).build();

        Text textDevilishGang = TextBuilder
                .create("devilish gang")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.RED)
                .setPosition(Align.BOTTOM_OF | Align.CENTER_OF, textThrowDamn).build();

        Text textSignsInTheAir = TextBuilder
                .create("signs in the air.")
                .setPaint(paint)
                .setSize(44)
                .setAlpha(0)
                .setColor(Color.RED)
                .setPosition(Align.BOTTOM_OF | Align.CENTER_OF, textDevilishGang).build();

        textSurface.play(
                new Sequential(
                        ShapeReveal.create(textDaai, 750, SideCut.show(Side.LEFT), false),
                        new Parallel(ShapeReveal.create(textDaai, 600, SideCut.hide(Side.LEFT), false), new Sequential(Delay.duration(300), ShapeReveal.create(textDaai, 600, SideCut.show(Side.LEFT), false))),
                        new Parallel(new TransSurface(500, textBraAnies, Pivot.CENTER), ShapeReveal.create(textBraAnies, 1300, SideCut.show(Side.LEFT), false)),
                        Delay.duration(500),
                        new Parallel(new TransSurface(750, textFokkenGamBra, Pivot.CENTER), Slide.showFrom(Side.LEFT, textFokkenGamBra, 750), ChangeColor.to(textFokkenGamBra, 750, Color.WHITE)),
                        Delay.duration(500),
                        new Parallel(TransSurface.toCenter(textHaai, 500), Rotate3D.showFromSide(textHaai, 750, Pivot.TOP)),
                        new Parallel(TransSurface.toCenter(textDaaiAnies, 500), Slide.showFrom(Side.TOP, textDaaiAnies, 500)),
                        new Parallel(TransSurface.toCenter(texThyLamInnie, 750), Slide.showFrom(Side.LEFT, texThyLamInnie, 500)),
                        Delay.duration(500),
                        new Parallel(
                                new TransSurface(1500, textSignsInTheAir, Pivot.CENTER),
                                new Sequential(
                                        new Sequential(ShapeReveal.create(textThrowDamn, 500, Circle.show(Side.CENTER, Direction.OUT), false)),
                                        new Sequential(ShapeReveal.create(textDevilishGang, 500, Circle.show(Side.CENTER, Direction.OUT), false)),
                                        new Sequential(ShapeReveal.create(textSignsInTheAir, 500, Circle.show(Side.CENTER, Direction.OUT), false))
                                )
                        ),
                        Delay.duration(200),
                        new Parallel(
                                ShapeReveal.create(textThrowDamn, 1500, SideCut.hide(Side.LEFT), true),
                                new Sequential(Delay.duration(250), ShapeReveal.create(textDevilishGang, 1500, SideCut.hide(Side.LEFT), true)),
                                new Sequential(Delay.duration(500), ShapeReveal.create(textSignsInTheAir, 1500, SideCut.hide(Side.LEFT), true)),
                                Alpha.hide(texThyLamInnie, 1500),
                                Alpha.hide(textDaaiAnies, 1500)
                        )
                )
        );

    

4. 使用

public class MainActivity extends AppCompatActivity 
    @BindView(R.id.text_surface)
    TextSurface mTextSurface;

    @Override
    protected void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ButterKnife.bind(this);

        mTextSurface.postDelayed(new Runnable() 
            @Override public void run() 
                show();
            
        , 1000);

        CheckBox checkDebug = (CheckBox) findViewById(R.id.check_debug);
        checkDebug.setChecked(Debug.ENABLED);
        checkDebug.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() 
            @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) 
                Debug.ENABLED = isChecked;
                mTextSurface.invalidate();
            
        );

    

    private void show() 
        mTextSurface.reset();
        CookieThumperSample.play(mTextSurface, getAssets());
