Divider
Android library providing a simple way to control divider items of RecyclerView.
Note: it only supports LinearLayoutManager by now
Setup
compile 'com.github.thepacific:divider:{lastestVersion}'
Usage
recyclerView.addItemDecoration(RecyclerViewDivider.builder(this)
.horizontal()//default is vertical
.leftMargin(R.dimen.divider_left)
.rightMargin(R.dimen.divider_right)
.topMargin(R.dimen.divider_top)
.bottomMargin(R.dimen.divider_bottom)
.leftMarginFactory(new RecyclerViewDivider.MarginFactory() {
@Override
public int getMargin(int position) {
return getResources().getDimensionPixelSize(R.dimen.divider_left);
}
})
.rightMarginFactory(new RecyclerViewDivider.MarginFactory() {
@Override
public int getMargin(int position) {
return getResources().getDimensionPixelSize(R.dimen.divider_right);
}
})
.topMarginFactory(new RecyclerViewDivider.MarginFactory() {
@Override
public int getMargin(int position) {
return getResources().getDimensionPixelSize(R.dimen.divider_top);
}
})
.bottomMarginFactory(new RecyclerViewDivider.MarginFactory() {
@Override
public int getMargin(int position) {
return getResources().getDimensionPixelSize(R.dimen.divider_bottom);
}
})
.color(R.color.divider, R.dimen.divider_stroke_width)
.drawable(R.drawable.divider)
.drawableFactory(new RecyclerViewDivider.DrawableFactory() {
@Override
public Drawable getDrawable(int position) {
return null;
}
@Override
public int getStrokeWidth(int position) {
return 0;
}
})
.displayFilter(new RecyclerViewDivider.DisplayFilter() {
@Override
public boolean isDisplay(int position) {
return false;
}
})
.hideLastDivider()
.build());
or
RecyclerViewDivider.builder(this).build().addTo(recyclerView);
DrawableFactory
When you are using a DrawableFactory, please be aware of this
new RecyclerViewDivider.DrawableFactory() {
@Override
public Drawable getDrawable(int position) {
/**
* When using ColorDrawable, don't forget to override {@link getStrokeWidth()}.
* Because ColorDrawable.getIntrinsicWidth() always returns -1.
* So we need {@link getStrokeWidth()} to provider ColorDrawable's size
* For example:
*
* <pre><code>
* new ColorDrawable(ContextCompat.getColor(MainActivity.this, R.color.divider));
* </code></pre>
*
* or
*
* <pre><code>
* <drawable name="divider">#303F9F</drawable>
* </code></pre>
*/
return null;
}
@Override
public int getStrokeWidth(int position) {
/**
* No need to override, when using XML Drawable resource.
* Because in this case Drawable.getIntrinsicWidth() always returns it's size.
* So {@link getStrokeWidth()} is useless.
* For example:
*
* divider.xml drawable
*
* <pre><code>
* <?xml version="1.0" encoding="utf-8"?>
* <shape xmlns:android="http://schemas.android.com/apk/res/android"
* android:shape="rectangle">
* <size android:height="1dp" android:width="1dp"></size>
* <solid android:color="@color/divider"></solid>
* </shape>
* </code></pre>
