BackdropEasy

A simple implementation of material design backdrop.

"A lot of flexibility not present, But quick to implement."

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

dependencies {
        implementation 'com.github.milindrc:BackdropEasy:v0.1'
}

Usage

public class TestActivity extends BackdropListActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);

    }

    @Override
    public int getMenu() {
	return R.menu.main;
    }

    @Override
    public Fragment getFragment(MenuItem item) {
	switch (item.getItemId()){
	    case R.id.a: getBinding().headerTitle.setText("Category A"); return BlankFragment.newInstance("A","");
	    case R.id.b: getBinding().headerTitle.setText("Category B"); return BlankFragment.newInstance("B", "");
	    case R.id.c: getBinding().headerTitle.setText("Category C"); return BlankFragment.newInstance("C", "");
	    case R.id.d: getBinding().headerTitle.setText("Category D"); return BlankFragment.newInstance("D", "");
	    case R.id.e: getBinding().headerTitle.setText("Category E"); return BlankFragment.newInstance("E", "");
	    case R.id.f: getBinding().headerTitle.setText("Category F"); return BlankFragment.newInstance("F", "");
	    case R.id.g: getBinding().headerTitle.setText("Category G"); return BlankFragment.newInstance("G", "");
	    default: return null;
	}
    }
}

Menu example:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">


    <group
	android:id="@+id/group"
	android:checkableBehavior="single"
	>
	<item
	    android:checkable="true"
	    android:id="@+id/a"
	    android:title="A" />
	<item
	    android:checkable="true"
	    android:id="@+id/b"
	    android:title="B" />
	<item
	    android:id="@+id/c"
	    android:checkable="true"
	    android:title="C" />
	<item
	    android:id="@+id/d"
	    android:checkable="true"
	    android:title="D" />
	<item
	    android:checkable="true"
	    android:id="@+id/e"
	    android:title="E" />
    </group>
