先看下滑动的效果图 滑动解锁分享的一个效果
https://github.com/TangfeiJi/SlideToUnlockProject 源码
我是以模块的方式导入的。看下操作的步骤
1.下载模块并导入在项目中。
2.在项目的Gradle中增加依赖
3.在布局中增加组件
<com.qdong.slide_to_unlock_view.CustomSlideToUnlockView
android:id="@+id/slide_to_unlock"
android:layout_width="match_parent"
android:layout_height="44dp"
android:layout_marginLeft="45dp"
android:layout_marginTop="50dp"
android:layout_marginRight="45dp"
android:layout_marginBottom="40dp"
chuck:slideImageViewResId="@mipmap/unlock_hide"
chuck:slideImageViewResIdAfter="@mipmap/unlock_1_hide"
chuck:slideImageViewWidth="35dp"
chuck:slideThreshold="0.5"
chuck:textColorResId="#fff"
chuck:textHint="滑动解锁"
chuck:textSize="6"
chuck:viewBackgroundResId="@drawable/shape_round_normal_green"
tools:ignore="MissingConstraints">
</com.qdong.slide_to_unlock_view.CustomSlideToUnlockView>
4.在activity中初始化并使用 这是列出它给出的监听
CustomSlideToUnlockView.CallBack callBack = new CustomSlideToUnlockView.CallBack() {
@Override//滑动到的位置
public void onSlide(int distance) {
Log.e("1111",distance+"");
}
@Override
public void onUnlocked() { //滑动到最后解锁
pop_layout.setVisibility(View.VISIBLE);
Toast.makeText(MainActivity.this,"onUnlocked",Toast.LENGTH_LONG).show();
}
};
