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

Answer 1

Based on the Robert's Answer, you can use the layout_marginLeft=-64dp to solve this problem easily.

However it doesn't seems to work anymore on Android 5.0 and above. So here's my solution that worked for me.

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    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"
    android:layout_marginRight="-64dp"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginRight="64dp"/>

    <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>

Basically, Add android:layout_marginRight="-64dp" to the root DrawerLayout so all the layout will go to the right for 64dp.

Then I add the layout_marginRight=64dp to the content so it goes back to the original position. Then you can have a full drawer there.

Answer 3

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

Here is a possible solution:

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);

        // 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 {
                throw new IllegalStateException("Child " + child + " at index " + i +
                        " does not have a valid layout_gravity - must be Gravity.LEFT, " +
                        "Gravity.RIGHT or Gravity.NO_GRAVITY");
            }
        }
    }

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

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

    int getDrawerViewGravity(View drawerView) {
        final int gravity = ((LayoutParams) drawerView.getLayoutParams()).gravity;
        return Gravity.getAbsoluteGravity(gravity, drawerView.getLayoutDirection());
    }

    static String gravityToString(int gravity) {
        if ((gravity & Gravity.LEFT) == Gravity.LEFT) {
            return "LEFT";
        }
        if ((gravity & Gravity.RIGHT) == Gravity.RIGHT) {
            return "RIGHT";
        }
        return Integer.toHexString(gravity);
    }

}

Answer 4

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);

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"/>

            android:layout_height="match_parent" />
    </FrameLayout>


    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="match_parent"
        android:layout_marginRight="32dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true">

        <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.
