Full width Navigation Drawer

Question

I'd like to create a full width navigation drawer. Setting layout_width to match_parent on @+id/left_drawer yields in width of about 80% of screen space. This seems to be the standard behavior. Do I have to override onMeasure() of DrawerLayout?

My current code:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/black"
        android:id="@+id/mainFragmentContainer">
    </FrameLayout>

    <include
        android:id="@+id/left_drawer"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        layout="@layout/drawer"/>
</android.support.v4.widget.DrawerLayout>

Thanks.

You can use this. Inspired by this post, I've upgraded for the 5th edition. Because it was having problems with StatusBar in versions 5 and later.

you have to extend DrawerLayout and override some methods because MIN_DRAWER_MARGIN is private

public class FullDrawerLayout extends DrawerLayout {

    private static final int MIN_DRAWER_MARGIN = 0; // dp

    public FullDrawerLayout(Context context) {
        super(context);
    }

    public FullDrawerLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FullDrawerLayout(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        final int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        final int widthSize = MeasureSpec.getSize(widthMeasureSpec);
        final int heightSize = MeasureSpec.getSize(heightMeasureSpec);

        if (widthMode != MeasureSpec.EXACTLY || heightMode != MeasureSpec.EXACTLY) {
            throw new IllegalArgumentException(
                    "DrawerLayout must be measured with MeasureSpec.EXACTLY.");
        }

        setMeasuredDimension(widthSize, heightSize);

        //for support Android 5+
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP) {
            FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) getLayoutParams();
            params.topMargin = getStatusBarHeight();
            setLayoutParams(params);
        }

        // Gravity value for each drawer we've seen. Only one of each permitted.
        int foundDrawers = 0;
        final int childCount = getChildCount();
        for (int i = 0; i < childCount; i++) {
            final View child = getChildAt(i);

            if (child.getVisibility() == GONE) {
                continue;
            }

            final LayoutParams lp = (LayoutParams) child.getLayoutParams();

            if (isContentView(child)) {
                // Content views get measured at exactly the layout's size.
                final int contentWidthSpec = MeasureSpec.makeMeasureSpec(
                        widthSize - lp.leftMargin - lp.rightMargin, MeasureSpec.EXACTLY);
                final int contentHeightSpec = MeasureSpec.makeMeasureSpec(
                        heightSize - lp.topMargin - lp.bottomMargin, MeasureSpec.EXACTLY);
                child.measure(contentWidthSpec, contentHeightSpec);
            } else if (isDrawerView(child)) {
                final int childGravity =
                        getDrawerViewGravity(child) & Gravity.HORIZONTAL_GRAVITY_MASK;
                if ((foundDrawers & childGravity) != 0) {
                    throw new IllegalStateException("Child drawer has absolute gravity " +
                            gravityToString(childGravity) + " but this already has a " +
                            "drawer view along that edge");
                }
                final int drawerWidthSpec = getChildMeasureSpec(widthMeasureSpec,
                        MIN_DRAWER_MARGIN + lp.leftMargin + lp.rightMargin,
                        lp.width);
                final int drawerHeightSpec = getChildMeasureSpec(heightMeasureSpec,
                        lp.topMargin + lp.bottomMargin,
                        lp.height);
                child.measure(drawerWidthSpec, drawerHeightSpec);
            } else {

                        " does not have a valid layout_gravity - must be Gravity.LEFT, " +

    boolean isContentView(View child) {
        return ((LayoutParams) child.getLayoutParams()).gravity == Gravity.NO_GRAVITY;

        final int gravity = ((LayoutParams) child.getLayoutParams()).gravity;
        final int absGravity = Gravity.getAbsoluteGravity(gravity,
                child.getLayoutDirection());
        return (absGravity & (Gravity.LEFT | Gravity.RIGHT)) != 0;
    }

    public int getStatusBarHeight() {
        int result = 0;
        int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");

            result = getResources().getDimensionPixelSize(resourceId);
        }
        return result;

Answer 3

you can by below code

 int width = getResources().getDisplayMetrics().widthPixels/2;
        DrawerLayout.LayoutParams params = (android.support.v4.widget.DrawerLayout.LayoutParams) drawer_Linear_layout.getLayoutParams();
        params.width = width;
        drawer_Linear_layout.setLayoutParams(params);

        <include layout="@layout/view_navigation_menu" />

    </android.support.design.widget.NavigationView>

</android.support.v4.widget.DrawerLayout>

That's works perfectly for me. Hope help others.

Answer 5

If you want simpler solution you can just set negative margin

android:layout_marginLeft="-64dp"

for your left_drawer:

<include
        android:id="@+id/left_drawer"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        layout="@layout/drawer"
        android:layout_marginLeft="-64dp"/>

Answer 6

Google recommends having a maxim width of 320 dip as per the UI guidelines here. Moreover, the width can be set by specified the layout_width of the left_drawer ListView.
