我在新的材质设计侧导航规范中看到，你可以在操作栏上方和状态栏后面显示抽屉。我如何实现这个?
当前回答
这里提到的所有答案都太旧太长了。与最新的Navigationview一起工作的最佳和简短的解决方案是
@Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
try {
//int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
// Do something for lollipop and above versions
Window window = getWindow();
// clear FLAG_TRANSLUCENT_STATUS flag:
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
// finally change the color to any color with transparency
window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDarktrans));}
} catch (Exception e) {
Crashlytics.logException(e);
}
}
这将改变你的状态栏颜色为透明当你打开抽屉
现在，当你关闭抽屉，你需要改变状态栏颜色再次为深色。你可以这样做。
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
try {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP){
// Do something for lollipop and above versions
Window window = getWindow();
// clear FLAG_TRANSLUCENT_STATUS flag:
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
// finally change the color again to dark
window.setStatusBarColor(getResources().getColor(R.color.colorPrimaryDark));}
} catch (Exception e) {
Crashlytics.logException(e);
}
}
然后在主布局中添加一行
android:fitsSystemWindows="true"
你的抽屉布局会是这样的
<android.support.v4.widget.DrawerLayout
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:id="@+id/drawer_layout"
android:fitsSystemWindows="true"
android:layout_width="match_parent"
android:layout_height="match_parent">
导航视图是这样的
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_height="match_parent"
android:layout_width="wrap_content"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/navigation_header"
app:menu="@menu/drawer"
/>
我已经测试过了，它完全可以工作。希望它能帮助到别人。这可能不是最好的方法，但它工作平稳，实现简单。 如果有用的话，做个记号。快乐编码:)
其他回答
以上所有的方法都是正确的，可能正在起作用。我已经按照上面的指南创建了一个工作演示，并在2上进行了测试。X至5.x
你可以从Github克隆
重要的事情是在主要活动中
toolbar = (Toolbar) findViewById(R.id.toolbar);
res = this.getResources();
this.setSupportActionBar(toolbar);
ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
ScrimInsetsFrameLayout scrimInsetsFrameLayout = (ScrimInsetsFrameLayout)
findViewById(R.id.linearLayout);
scrimInsetsFrameLayout.setOnInsetsCallback(this);
}
还有回调
@Override
public void onInsetsChanged(Rect insets) {
Toolbar toolbar = this.toolbar;
ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams)
toolbar.getLayoutParams();
lp.topMargin = insets.top;
int top = insets.top;
insets.top += toolbar.getHeight();
toolbar.setLayoutParams(lp);
insets.top = top; // revert
}
V21的主题绝对有魔力
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- API 21 theme customizations can go here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/accent_material_light</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">true</item>
</style>
和ScrimInsetsFrameLayout
现在有了新的设计支持库，这变得更容易了
compile 'com.android.support:design:22.2.0'
克隆来自@Chris Banes https://github.com/chrisbanes/cheesesquare
这是最简单的，对我来说很管用:
在值-21中:
<resources>
<style name="AppTheme" parent="AppTheme.Base">
...
<item name="android:windowTranslucentStatus">true</item>
</style>
<dimen name="topMargin">25dp</dimen>
</resources>
在值中:
<resources>
<dimen name="topMargin">0dp</dimen>
</resources>
并设置到工具栏
android:layout_marginTop="@dimen/topMargin"

试试这个:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/drawer_layout"
android:fitsSystemWindows="true">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!--Main layout and ads-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="@+id/ll_main_hero"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</FrameLayout>
<FrameLayout
android:id="@+id/ll_ads"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<View
android:layout_width="320dp"
android:layout_height="50dp"
android:layout_gravity="center"
android:background="#ff00ff" />
</FrameLayout>
</LinearLayout>
<!--Toolbar-->
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/toolbar"
android:elevation="4dp" />
</FrameLayout>
<!--left-->
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@null"
android:background="@mipmap/layer_image"
android:id="@+id/left_drawer"></ListView>
<!--right-->
<FrameLayout
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="@mipmap/layer_image">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@mipmap/ken2"
android:scaleType="centerCrop" />
</FrameLayout>
风格:
<style name="ts_theme_overlay" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">@color/red_A700</item>
<item name="colorPrimaryDark">@color/red1</item>
<item name="android:windowBackground">@color/blue_A400</item>
</style>
Main Activity扩展了ActionBarActivity
toolBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolBar);
现在你可以像使用工具栏一样使用createoptionsmenu。
这是我的布局
上:左抽屉-右抽屉 中:工具栏(ActionBar) 底部:ListFragment
希望你能理解!玩得开心!
编辑:新的设计支持库支持这一点，不再需要以前的方法。
现在可以使用新的Android设计支持库来实现这一点。
你可以看到Chris Banes的Cheesesquare样本应用，它演示了所有的新功能。
以前的方法:
由于没有完整的解决方案，这里是我实现预期结果的方法。
首先在你的项目中包含一个ScrimInsetsFrameLayout。

/**
* A layout that draws something in the insets passed to
* {@link #fitSystemWindows(Rect)}, i.e. the area above UI chrome
* (status and navigation bars, overlay action bars).
*/
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_insetForeground);
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);
}
}
/**
* Allows the calling container to specify a callback for custom
* processing when insets change (i.e. when {@link #fitSystemWindows(Rect)}

* When using with ListView or GridView, remember to set
* clipToPadding to false.
*/
public void setOnInsetsCallback(OnInsetsCallback onInsetsCallback) {
mOnInsetsCallback = onInsetsCallback;
}
public static interface OnInsetsCallback {
public void onInsetsChanged(Rect insets);
}
}
然后创建一个可样式，这样inset前台就可以设置了。
值/ attrs.xml
<declare-styleable name="ScrimInsetsView">
<attr name="insetForeground" format="reference|color" />
</declare-styleable>
更新你的活动的xml文件，并确保android:fitsSystemWindows设置为true在DrawerLayout以及ScrimInsetsFrameLayout。
布局/ activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<!-- The main content view -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- Your main content -->
</LinearLayout>
<!-- The navigation drawer -->
<com.example.app.util.ScrimInsetsFrameLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/scrimInsetsFrameLayout"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/white"
android:elevation="10dp"
android:fitsSystemWindows="true"
app:insetForeground="#4000">
<!-- Your drawer content -->
</com.example.app.util.ScrimInsetsFrameLayout>
</android.support.v4.widget.DrawerLayout>
在活动的onCreate方法中，设置抽屉布局上的状态栏背景色。
MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// ...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mDrawerLayout.setStatusBarBackgroundColor(
getResources().getColor(R.color.primary_dark));
}
最后更新应用程序的主题，使DrawerLayout位于状态栏的后面。
values-v21 / styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
