在 Android 的 DrawerLayout 中设置状态栏颜色

Question

我想在我的自定义DrawerLayout 中设置状态栏颜色，就像默认导航抽屉一样。它工作得很好，但DraweeLayout 应该在状态栏后面，状态栏颜色应该是自定义的。 下面是我的 v21\style。

<resources>
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:statusBarColor">@color/orange</item>
</style>

这是activity_main.xml

    <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"
    android:fitsSystemWindows="false">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="vertical"
        >
        <android.support.v7.widget.Toolbar
            android:id="@+id/my_awesome_toolbar"
            android:layout_height="80dp"
            android:layout_width="match_parent"
            android:minHeight="?attr/actionBarSize"
            android:background="@color/orange"
            android:fitsSystemWindows="true"
            />
    </LinearLayout>

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="50dp">

        <LinearLayout
            android:id="@+id/llFirst"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:background="@color/orange"
            android:layout_marginTop="25dp"
            android:orientation="horizontal">

            <ImageView
                android:id="@+id/imgMenu"
                android:layout_width="30dp"
                android:layout_height="30dp"
                android:layout_gravity="center"
                android:src="@drawable/menu" />
        </LinearLayout>
    </FrameLayout>

    <ExpandableListView
        android:id="@+id/lvLeft"
        android:layout_width="280dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/white"
        android:choiceMode="singleChoice"
        android:dividerHeight="0dp"
        />    
</android.support.v4.widget.DrawerLayout>

这是我的 MainActivity。

        drawerLayoutAdapter = new MyAdapter(MainActivity.this, arrayList);
        expandbleLis.setAdapter(drawerLayoutAdapter);
        expandbleLis.setOnChildClickListener(this);
    }

    private void setListner()

        });

        arrayList = new ArrayList<MyModel>();

    }

实际上我想实现自定义抽屉布局，其中状态栏颜色应该是自定义的，并且抽屉布局应该在状态栏后面，它是半透明的。在这里，我附上了图片，我想实现相同。我已经尝试了几乎所有的解决方案，但没有得到任何正确的结果，所以请帮我解决这个问题。提前致谢。

Answer 1

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/statusbar_color</item>
    <item name="colorPrimaryDark">@color/statusbar_color</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

将该代码添加到您的 style.XML 中，然后在您喜欢的应用程序标记集中应用到您的清单中。 ..

 android:theme="@style/AppTheme"

Answer 2

我想你正在寻找ScrimInsetsFrameLayout。

这是自定义ScrimInsetsFrameLayout 类，您可以使用它来实现这种行为

ScrimInsetsFrameLayout.java

public class ScrimInsetsFrameLayout extends FrameLayout {
    private Drawable mInsetForeground;

    private Rect mInsets;
    private Rect mTempRect = new Rect();
    private OnInsetsCallback mOnInsetsCallback;

    public ScrimInsetsFrameLayout(Context context) {
        super(context);
        init(context, null, 0);
    }

    public ScrimInsetsFrameLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context, attrs, 0);
    }

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

    private void init(Context context, AttributeSet attrs, int defStyle) {
        final TypedArray a = context.obtainStyledAttributes(attrs,
                R.styleable.ScrimInsetsView, defStyle, 0);
        if (a == null) {
            return;
        }
        mInsetForeground = a
                .getDrawable(R.styleable.ScrimInsetsView_insetForeground1);
        a.recycle();

        setWillNotDraw(true);
    }

    @Override
    protected boolean fitSystemWindows(Rect insets) {
        mInsets = new Rect(insets);
        setWillNotDraw(mInsetForeground == null);
        ViewCompat.postInvalidateOnAnimation(this);
        if (mOnInsetsCallback != null) {
            mOnInsetsCallback.onInsetsChanged(insets);
        }
        return true; // consume insets
    }

    @Override
    public void draw(Canvas canvas) {
        super.draw(canvas);

        int width = getWidth();
        int height = getHeight();
        if (mInsets != null && mInsetForeground != null) {
            int sc = canvas.save();
            canvas.translate(getScrollX(), getScrollY());

            // Top
            mTempRect.set(0, 0, width, mInsets.top);
            mInsetForeground.setBounds(mTempRect);
            mInsetForeground.draw(canvas);

            // Bottom
            mTempRect.set(0, height - mInsets.bottom, width, height);
            mInsetForeground.setBounds(mTempRect);
            mInsetForeground.draw(canvas);

            // Left
            mTempRect
                    .set(0, mInsets.top, mInsets.left, height - mInsets.bottom);
            mInsetForeground.setBounds(mTempRect);
            mInsetForeground.draw(canvas);

            // Right
            mTempRect.set(width - mInsets.right, mInsets.top, width, height
                    - mInsets.bottom);
            mInsetForeground.setBounds(mTempRect);
            mInsetForeground.draw(canvas);

            canvas.restoreToCount(sc);
        }
    }

    @Override
    protected void onAttachedToWindow() {
        super.onAttachedToWindow();
        if (mInsetForeground != null) {
            mInsetForeground.setCallback(this);
        }
    }

    @Override
    protected void onDetachedFromWindow() {
        super.onDetachedFromWindow();
        if (mInsetForeground != null) {
            mInsetForeground.setCallback(null);
        }
    }

    public void setOnInsetsCallback(OnInsetsCallback onInsetsCallback) {
        mOnInsetsCallback = onInsetsCallback;
    }

    public static interface OnInsetsCallback {
        public void onInsetsChanged(Rect insets);
    }
}

现在关于这个类的使用。

->activity_main.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true" >

    <RelativeLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true" >

        <include
            android:id="@+id/toolbar_headers"
            layout="@layout/toolbar_header"
            android:visibility="invisible" />
    </RelativeLayout>

    <yourpackagename.ScrimInsetsFrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:layout_marginRight="-8dp"
        android:elevation="8dp"
        android:fitsSystemWindows="true"
        app:insetForeground1="#4000" >

        <!-- this would be your custom drawer layout -->
        <include
            android:id="@+id/drawar_layout"
            layout="@layout/drawar_layout" />
    </bhagyagold.com.extraclasses.ScrimInsetsFrameLayout>

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

这里的无能标签是android:fitsSystemWindows，请仔细检查所有视图。

->java部分

最终使用此布局打开或关闭您的抽屉。

例如

mLayout = (ScrimInsetsFrameLayout) findViewById(R.id.container);
mDrawerLayout.closeDrawer(mLayout);

->styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light">
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">colorPrimaryDark</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
        <item name="android:windowContentTransitions">true</item>
        <item name="android:windowAllowEnterTransitionOverlap">true</item>
        <item name="android:windowAllowReturnTransitionOverlap">true</item>
        <item name="android:windowSharedElementEnterTransition">@android:transition/move</item>
        <item name="android:windowSharedElementExitTransition">@android:transition/move</item>
        <item name="windowNoTitle">true</item>
    </style>

编辑：

-> attrs.xml

<resources>

    <declare-styleable name="ScrimInsetsView">
        <attr name="insetForeground1" format="reference|color" />
    </declare-styleable>

</resources>

编码愉快..
