I have a DrawerLayout which the first time when I swipe it, it is coming in steps(like lag or something similar), but after that it moves fine. I don't know what code to post, because as I said it's working fine, only the first time when I open it, it doesn't open smoothly.
This is my layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/DrawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:elevation="7dp">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="name.company.newapp.HomeScreen"
tools:showIn="@layout/activity_home_screen">
<FrameLayout
android:id="@+id/your_placeholder"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/RecyclerView"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#ffffff"
android:scrollbars="vertical">
</android.support.v7.widget.RecyclerView>
</android.support.v4.widget.DrawerLayout>
onCreate method
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_screen);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
mRecyclerView = (RecyclerView) findViewById(R.id.RecyclerView); // Assigning the RecyclerView Object to the xml View
LinearLayoutManager mLayoutManager = new LinearLayoutManager(this);
mLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mAdapter = new MyDrawerAdapter(TITLES,ICONS,NAME,EMAIL,PROFILE,this);
mRecyclerView.setAdapter(mAdapter); // Setting the adapter to RecyclerView
mRecyclerView.setHasFixedSize(true); // Letting the system know that the list objects are of fixed size
final GestureDetector mGestureDetector = new GestureDetector(HomeScreen.this, new GestureDetector.SimpleOnGestureListener() {
@Override public boolean onSingleTapUp(MotionEvent e) {
return true;
}
});
mRecyclerView.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
@Override
public boolean onInterceptTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
View child = recyclerView.findChildViewUnder(motionEvent.getX(), motionEvent.getY());
if (child != null && mGestureDetector.onTouchEvent(motionEvent)) {
switch(recyclerView.getChildAdapterPosition(child)){
case 1:setFragment(new PreferencesFragment());
break;
default:
Toast.makeText(HomeScreen.this, "The Item Clicked is: " + recyclerView.getChildAdapterPosition(child), Toast.LENGTH_SHORT).show();
}
Drawer.closeDrawers();
return true;
}
return false;
}
@Override
public void onTouchEvent(RecyclerView recyclerView, MotionEvent motionEvent) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
});
Drawer = (DrawerLayout) findViewById(R.id.DrawerLayout); // Drawer object Assigned to the view
mDrawerToggle = new ActionBarDrawerToggle(this,Drawer,toolbar,R.string.navigation_drawer_open,R.string.navigation_drawer_close){
@Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
// code here will execute once the drawer is opened( As I dont want anything happened whe drawer is
// open I am not going to put anything here)
}
@Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
// Code here will execute once drawer is closed
}
}; // Drawer Toggle Object Made
Drawer.setDrawerListener(mDrawerToggle); // Drawer Listener set to the Drawer toggle
mDrawerToggle.syncState(); // Finally we set the drawer toggle sync State
}
Edit: I might have found a solution here Why does DrawerLayout sometimes glitch upon opening? , but I don't know how to implement it in my code.
