问:
我怎么能有标题了?
下面是截图(缺少标题):
动作条设置:
动作条动作条= getSupportActionBar();
actionBar.setTitle(我的标题);
actionBar.setIcon(drawable.dropdown_user);
查看mLogoView = LayoutInflater.from(本).inflate(R.layout.mLogoView,NULL);
actionBar.setCustomView(mLogoView);
actionBar.setDisplayShowCustomEnabled(真正的);
actionBar.setDisplayShowTitleEnabled(真正的);
actionBar.setDisplayHomeAsUpEnabled(真正的);
mLogoView.xml:
< XML版本=1.0编码=UTF-8&GT?;
< RelativeLayout的的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =WRAP_CONTENT
机器人:layout_height =match_parent>
< ImageView的
机器人:ID =@ + ID / img_merchant
机器人:layout_width =WRAP_CONTENT
机器人:layout_height =WRAP_CONTENT
机器人:layout_alignParentRight =真
机器人:SRC =@可绘制/ infoflex>
< / ImageView的>
< / RelativeLayout的>
解决方案
这是我能想到的方式来解决这个问题的第一件事是尝试设置
< RelativeLayout的的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =WRAP_CONTENT
机器人:layout_height =match_parent
机器人:layout_gravity =权与GT;
你的 RelativeLayout的
。因为作为默认的Android中每一个观点是由左到右(如果你不指定在code别的东西)补充说。
如果不工作,我想补充机器人:layout_width =90dip
或依赖的形象和你的测试一些其他的价值。第二个选项是更像是一种解决方法,但我认为它会在所有的设备上。
编辑:
当我发现有使用一点小问题 RelativeLayout的
和动作条自定义视图,从而更好的选择是使用的LinearLayout
,并通过code设置的LayoutParams
。修改XML看起来是这样的:
< XML版本=1.0编码=UTF-8&GT?;
< LinearLayout中的xmlns:机器人=http://schemas.android.com/apk/res/android
机器人:layout_width =WRAP_CONTENT
机器人:layout_height =WRAP_CONTENT>
< ImageView的
机器人:layout_width =WRAP_CONTENT
机器人:layout_height =WRAP_CONTENT
机器人:SRC =@可绘制/ ASUS/>
< / LinearLayout中>
和你MainActivity.class使用这样的:
进口com.actionbarsherlock.app.ActionBar.LayoutParams;
....
动作条动作条= getSupportActionBar();
actionBar.setTitle(OMG);
的LayoutParams LP =新的LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT,Gravity.RIGHT | Gravity.CENTER_VERTICAL);
查看customNav = LayoutInflater.from(本).inflate(R.layout.img,NULL); //布局,其中包含您的按钮。
actionBar.setCustomView(customNav,LP);
actionBar.setDisplayShowCustomEnabled(真正的);
Question:
How can I have the title back?
Here's the screenshot (Missing title):
Actionbar setting:
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("My Title");
actionBar.setIcon(drawable.dropdown_user);
View mLogoView = LayoutInflater.from(this).inflate(R.layout.mLogoView, null);
actionBar.setCustomView(mLogoView);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
mLogoView.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<ImageView
android:id="@+id/img_merchant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="@drawable/infoflex">
</ImageView>
</RelativeLayout >
解决方案
The first thing which I can think a way to fix that is try to set
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right" >
to your RelativeLayout
. Because as default in Android every View is added from left to right (if you doesn't specify something else in your code).
And if that doesn't work, I would add android:layout_width="90dip"
or some other value depending on the image and your tests. The second option is more like a workaround, but I think it will work on all devices.
Edit:
As I found there is a little problem using RelativeLayout
and Custom Views in ActionBar, so the better option is to use LinearLayout
and set LayoutParams
via code. Change your xml to look like this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/asus" />
</LinearLayout >
and in your MainActivity.class use this :
import com.actionbarsherlock.app.ActionBar.LayoutParams;
....
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("OMG");
LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.RIGHT | Gravity.CENTER_VERTICAL);
View customNav = LayoutInflater.from(this).inflate(R.layout.img, null); // layout which contains your button.
actionBar.setCustomView(customNav, lp);
actionBar.setDisplayShowCustomEnabled(true);
