问题描述

我已经对这个主题做了一些研究,但是我找不到一些针对我的App / Activity的解决方案。

I've done a few researches on this topic but I couldn't found some solution for my App/ Activity.


  1. 我试图获得一个透明的操作栏。

首先,我尝试更改AndroidManifest.xml中的主题:

First, I have tried to change the themes in my AndroidManifest.xml:

values / styles.xml:

<style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
    <item name="android:windowContentOverlay">@null</item>
    <item name="windowActionBarOverlay">true</item>
    <item name="colorPrimary">@android:color/transparent</item>

值 - v21 / styles.xml:

  <style name="AppTheme.ActionBar.Transparent" parent="AppTheme">
        <item name="colorPrimary">@android:color/transparent</item>
    </style>

但结果如下:

所以我只是得到了一些亮点灰色动作条左侧/右侧有一些间隙。

So I only get some light grey action bar with some gaps on the left/ right side.

其次,我尝试过使用 fitsSystemWindow =true android:background =我的布局中有@android:color / transparent,但它也没有解决问题。

Second, I have tried using fitsSystemWindow="true" and android:background="@android:color/transparent" in my layouts, but it also didn't fix the issue.

 <?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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:fitsSystemWindows="true"
    tools:context="com.example.poweranimal.letsgo.Application.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@android:color/transparent">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"/>


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

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

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

但我得到的输出与以前相同:( 2.另外我也试过了透明状态栏:

But I get the same output as before:( 2. In addition I have tried also the get a transparent status bar with:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

<item name="android:statusBarColor">@android:color/transparent</item>

但这没有也没有工作(没有改变)。

but this didn't work too (nothing has changed).

我真正想要的是这样的:

What I actually want is something like this:

如果有人有,那会很酷对我来说可能是一个解决方案。

Would be cool if anyone has a possible solution for me.

提前致谢。

推荐答案

1。首先,您必须更改布局结构,以在透明<下显示 MAP code>工具栏& StatusBar 还要删除从您现有的工具栏中左右 gap

1. First, you have to change your layout structure to show MAP under transparent Toolbar & StatusBar and also to remove left and right gap from your existing Toolbar.

activity_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    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:fitsSystemWindows="false">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:layout_marginTop="24dp"
            android:elevation="1dp" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/sample_map">

            <!-- put your content here -->

        </LinearLayout>
    </RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

2。 MainActivity ,在下面做一些事情来初始化工具栏并使工具栏 StatusBar as transparent

2. In your MainActivity, do below things to initialize Toolbar and make Toolbar and StatusBar as transparent.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

    // Toolbar :: Transparent
    toolbar.setBackgroundColor(Color.TRANSPARENT);

    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle("StackOverflow");
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);

    // Status bar :: Transparent
    Window window = this.getWindow();

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
    {
        window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
        window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
        window.setStatusBarColor(Color.TRANSPARENT);
    }

    ...........
    .................. 
}

3。将以下主题应用于 MainActivity

values / styles.xml:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    .......
    ...........

</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

AndroidManifest.xml:

<activity
    android:name=".EmptyActivity"
    android:theme="@style/AppTheme.NoActionBar">

</activity>

输出:

仅供参考,我刚刚在我的内容中使用了地图的示例图片 LinearLayout 显示行为。对于您的情况,将所有内容(搜索栏,地图)放入其中。

FYI, I have just used an sample image of map in my content LinearLayout to show the behavior. For your case put all of your content(searchbar, map) inside it.

希望这会有所帮助〜
