I am unable to get menu items in my toolbar. I am using android.support.v4.widget.DrawerLayout for my layout file.
I have menu_settings:
<menu 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"
tools:context="com.example.shiza.muslimmemo.Settings">
<item
android:id="#+id/back"
android:orderInCategory="100"
android:title="Back"
android:icon="#drawable/ic_keyboard_backspace"
app:showAsAction="always" />
</menu>
and the Settings activity:
package com.example.shiza.muslimmemo;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class Settings extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_settings, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.back) {
Intent intent = new Intent(this,MainActivity.class);
startActivity(intent);
}
return super.onOptionsItemSelected(item);
}
}
and finally,the settings_xml,
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
</android.support.v4.widget.DrawerLayout>
But I can't see any ic_keyboard_backspace in my toolbar. Please help me out.
I believe you should set your toolbar as the window action bar, orAppCompatActivity won't know where to inflate your menu. Try using this onCreate method:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
Toolbar t = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(t);
}

So I want to implement a Bottom Sheet behavior and everything works fine except at first (when activity is created) the bottom sheet is not positioned how I configured it.
I can't find any information on why this is happening or if it is some configuration I am missing.
I prepared a sample code and some images to show the problem:
The activity (I haven't done anything, this is the initial template)
package com.example.testbottomsheet;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
The Layout
<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">

<LinearLayout

app:behavior_peekHeight="40dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<ImageView

android:layout_width="match_parent"
android:layout_height="40dp"

android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#156de8"></FrameLayout>
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
As one can see I have a peekHeight of 40dp, and it works fine after I expand and close it )or just a small flick on top of the bottom sheet), however it is not initially set like this. I colored everything to be easier to spot:
Open Pane
Should-be initial state
IS initial state
From what I could see the bottom sheet is being placed 20dp bellow of the desired number configured in the XML.
Its a bug in design support lib.. take a look at this link:
https://code.google.com/p/android/issues/detail?id=203057
Try adding android:fitsSystemWindows="true" to the LinearLayout that you have added the BottomSheetBehaviour to.
I am having problems with ListView. It doesn't display. I know it's a common problem but I'm new to Android. In most examples, the problem is solved with layout_bellow property but I do not have any other controls.
Here is my XML code:
Here is my activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<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="com.gkmicro.trrrrrrrrrrrrrr.MainActivity"
tools:showIn="#layout/activity_main">
<ListView
android:id="#+id/myListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
And here is my MainActivity.java:
package com.gkmicro.trrrrrrrrrrrrrr;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
As your ListView is android:layout_alignParentBottom="true" it stick to bottom with android:layout_height="wrap_content"
So make ListView like this
<ListView
android:id="#+id/myListView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
/>
Change your ListView to use all width and height of your parent RelativeLayout
<?xml version="1.0" encoding="utf-8"?>
<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="com.gkmicro.trrrrrrrrrrrrrr.MainActivity"
tools:showIn="#layout/activity_main">
<ListView
android:id="#+id/myListView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
By the way as recommended #Erik Jhordan Rey Caffrey use RecyclerView
EDIT: If you have any issues here is a good sample to implement a simple listView inside a RelativeLayout
Hope this helps!
I am trying to use the android navigation drawer with the action bar of AppCompatActivity. But when I implement the action bar the icon to open the navigation drawer is missing in it.
This is what I want to be displayed
This is a screenshot of my current action bar
You can see my code below.
This is my activity_main.xml

android:layout_width="match_parent"
android:layout_height="wrap_content" />
<!-- The main content view where fragments are loaded -->
<FrameLayout
android:id="#+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<!-- The navigation drawer that comes from the left -->
<!-- Note that `android:layout_gravity` needs to be set to 'start' -->

This is my MainActivity

}
return super.onOptionsItemSelected(item);
}
}
Why is the icon to open the navigation drawer missing using my code?
You didn't implement the NavigationDrawer in your Activityi guess.i've had the same problem and that fixed with the following code.
In your Activity:
private DrawerLayout drawerLayout;
In your onCreate:
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
if (menuItem.isChecked()) menuItem.setChecked(false);
else menuItem.setChecked(true);
drawerLayout.closeDrawers();
switch (menuItem.getItemId()) {
case R.id.home:
drawerLayout.closeDrawers();
return true;
default:
return true;
}
}
});
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
ActionBarDrawerToggle actionBarDrawerToggle =
new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawerLayout.setDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
Strings.xml:
<string name="openDrawer">Navigation</string>
<string name="closeDrawer">Close Navigation</string>
Then it should work.
Try this code,
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
You may need to include:
actionBarDrawerToggle.syncState();

Just go to your Fragment_navigation class and
replace

with
