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;
}
}
}
