使用说明

添加 Gradle 依赖

Download bga-transformerstip 后面的「latestVersion」指的是左边这个 Download 徽章后面的「数字」,请自行替换。

dependencies {
    implementation 'cn.bingoogolapple:bga-transformerstip:latestVersion@aar'
}

方式一:在 Java 代码中设置浮窗位置、浮窗背景、箭头位置

  • 添加浮窗布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="10dp"
    android:paddingBottom="16dp"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"
    android:background="@color/colorPrimaryDarkTrans"
    android:gravity="center_vertical"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/tv_tip_content"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:text="这里 paddingBottom 比其他 padding 多了 6pd 是为了留空间给三角箭头"
        android:textColor="@android:color/white" />

    <TextView
        android:id="@+id/tv_tip_close"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="10dp"
        android:layout_gravity="top"
        android:padding="4dp"
        android:text="X"
        android:textColor="@android:color/white" />
</LinearLayout>
  • 在 Java 代码中设置浮窗位置、浮窗背景、箭头位置
new TransformersTip(anchorView, R.layout.layout_demo1_tip) {
    @Override
    protected void initBackground(View contentView) {
        // 在 Java 代码中设置浮窗背景以及箭头位置
        new ArrowDrawable(contentView)
                .setArrowGravity(ArrowGravity.TO_BOTTOM_CENTER) // 设置箭头相对于浮窗的位置
                .setBgColorRes(R.color.colorPrimaryDarkTrans) // 设置背景色
                .setArrowHeightDp(6) // 设置箭头高度
                .setRadiusDp(4) // 设置浮窗圆角半径
                .setArrowOffsetXDp(0) // 设置箭头在 x 轴的偏移量
                .setArrowOffsetYDp(0); // 设置箭头在 y 轴的偏移量
    }

    @Override
    protected void initView(View contentView) {
        // 点击浮窗中自定按钮关闭浮窗
        contentView.findViewById(R.id.tv_tip_close).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
    }
}.setTipGravity(TipGravity.TO_TOP_CENTER) // 设置浮窗相对于锚点控件展示的位置
        .setTipOffsetXDp(0) // 设置浮窗在 x 轴的偏移量
        .setTipOffsetYDp(0) // 设置浮窗在 y 轴的偏移量
        .show(); // 显示浮窗

方式二:在 Java 代码中设置浮窗位置,在布局文件中设置浮窗背景、箭头位置

  • 添加浮窗布局文件,在布局文件中设置浮窗背景、箭头位置。优点是可以提前预览效果
<?xml version="1.0" encoding="utf-8"?>
<cn.bingoogolapple.transformerstip.view.TransformersTipLinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingTop="16dp"
    android:paddingBottom="10dp"
    android:paddingStart="10dp"
    android:paddingEnd="10dp"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    app:ad_arrowExtraOffsetX="0dp"
    app:ad_arrowExtraOffsetY="0dp"
    app:ad_arrowGravity="to_top_center"
    app:ad_arrowHeight="6dp"
    app:ad_background="@color/colorPrimaryDarkTrans"
    app:ad_radius="4dp">

    <TextView
        android:id="@+id/tv_tip_content"
        android:layout_width="200dp"
        android:layout_height="wrap_content"
        android:text="这里 paddingTop 比其他 padding 多了 6pd 是为了留空间给三角箭头"
        android:textColor="@android:color/white" />

    <TextView
        android:id="@+id/tv_tip_close"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="10dp"
        android:layout_gravity="top"
        android:padding="4dp"
        android:text="X"
        android:textColor="@android:color/white" />
</cn.bingoogolapple.transformerstip.view.TransformersTipLinearLayout>
  • 在 Java 代码中设置浮窗位置
new TransformersTip(anchorView, R.layout.layout_demo2_tip) {
    @Override
    protected void initView(View contentView) {
        // 点击浮窗中自定按钮关闭浮窗
        contentView.findViewById(R.id.tv_tip_close).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dismiss();
            }
        });
    }
}.setTipGravity(TipGravity.TO_BOTTOM_CENTER) // 设置浮窗相对于锚点控件展示的位置
        .setTipOffsetXDp(0) // 设置浮窗在 x 轴的偏移量
        .setTipOffsetYDp(0) // 设置浮窗在 y 轴的偏移量
        .show(); // 显示浮窗

TipGravity 说明

  • 通过 TipGravity.xxxx 来设置浮窗相对于锚点控件展示的位置 TipGravity说明

ArrowGravity 说明

  • 通过 ArrowGravity.xxxx 来设置箭头相对于浮窗的位置
