如何设置Android工具栏高度? [英] How to set Android toolbar height?

问题描述

我想实现这一目标:

我想做的是制作一个具有更高高度的自定义工具栏，并正常使用tabhost和tabpager.我已经实现了它，但是工具栏显示的是正常高度，因此它并没有显示出我想要的高度，只是顶部.这是正确的方法还是可以在线性/相对布局下面设置TabHost?因为我不需要将其用作操作栏.

What I thought was to make a Custom Toolbar with a bigger height and work with the tabhost and tabpager normally. I have implemented it, but the toolbar is showing the normal height, so it doesn't show as I want, just the top part. Is this the right approach or is it possible to set a TabHost below a Linear/Relative Layout? Because I don't need to work with it as an action bar.

活动"中的此功能:

private void setupActionBar()
    {
        ActionBar ab = getSupportActionBar();
        ab.setDisplayShowCustomEnabled(true);
        ab.setDisplayShowTitleEnabled(false);
        LayoutInflater inflator = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View v = inflator.inflate(R.layout.toolbar_title, null);
        ab.setCustomView(v);
    }

推荐答案

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/toolbarTitle"
android:orientation="vertical"
android:background="@color/black"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:minHeight="?attr/actionBarSize" //pay attention here
android:theme="@style/AppTheme"
android:layout_height="wrap_content"> //pay attention here

您的ToolBar是ViewGroup，它的高度环绕其子级，这意味着只有对子级进行测量后，它的大小才会固定.您的最小身高在50到60 dip左右，这就是您的ToolBar的最低高度. 因此，如果您的孩子的身高未加到一个合理的大数字，则仍为<= 50

your ToolBar which is a ViewGroup is wraping its height around its children meaning it will get a fixed size only if the children are measured. your minimum height is around 50 to 60 dip, that is how low your ToolBar will be. so if your children height do not add up to a reasonable big number it will still be <= 50

给它一个首选的高度android:layout_height="200dp"
