我有问题。我有一个支持操作栏,我在其中设置了一个图像。问题是图像略微向右。我认为这是一个兼容性问题。
以下是图片的屏幕截图:
正如您所看到的,actionBar中的图像略微向右(如果它不可见,请相信我)。
当我使用actionBar时,图像最初正确居中,但是当我将appcompat添加到项目时,getActionBar()开始返回null,并且应用程序崩溃了。我搜索了互联网并得到了getSupportActionBar()方法。这次应用程序没有崩溃,但图像没有像以前那样正确居中。我怀疑这是主题/兼容性/重写的事情,或类似的事情。
任何人都可以帮助我吗?
以下是我调用操作栏的方法:
public void initializeActionBar() {
getSupportActionBar();
getSupportActionBar().setDisplayShowCustomEnabled(true);
getSupportActionBar().setCustomView(com.entu.bocterapp.R.layout.action_bar_center_image);
getSupportActionBar().setBackgroundDrawable(new ColorDrawable(0xff50aaf1));
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
以下是" R.layout.action_bar_center_image"的XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal">
<ImageView
android:id="@+id/bocterAppLogo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/bocterapp"
android:contentDescription=""/>
</LinearLayout>
这是gradle.build:
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'com.android.tools.build:gradle:1.0.0-rc1'
}
}
apply plugin: 'android'
dependencies {
compile fileTree(include: '*.jar', dir: 'libs')
compile files('libs/Parse-1.7.0/Parse-1.7.0.jar')
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.google.android.gms:play-services:6.5.87'
}
android {
signingConfigs {
config {
storeFile file('C:/bocterapp.keystore')
}
}
compileSdkVersion 21
buildToolsVersion '21.1.1'
sourceSets {
main {
manifest.srcFile 'AndroidManifest.xml'
java.srcDirs = ['src']
resources.srcDirs = ['src']
aidl.srcDirs = ['src']
renderscript.srcDirs = ['src']
res.srcDirs = ['res']
assets.srcDirs = ['assets']
}
// Move the tests to tests/java, tests/res, etc...
instrumentTest.setRoot('tests')
// Move the build types to build-types/<type>
// For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
// This moves them out of them default location under src/<type>/... which would
// conflict with src/ being used by the main source set.
// Adding new build types or product flavors should be accompanied
// by a similar customization.
debug.setRoot('build-types/debug')
release.setRoot('build-types/release')
}
dexOptions {
preDexLibraries = false
}
}
以下是款式:
样式:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<!--
Base application theme, dependent on API level. This theme is replaced
by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
<!--
Theme customizations available in newer API levels can go in
res/values-vXX/styles.xml, while customizations related to
backward-compatibility can go here.

</style>
<!-- Application theme. -->

有人可以帮助我吗? 干杯!

使用AppCompat 21,操作栏由工具栏小部件表示。
在您的活动布局中添加android.support.v7.widget.Toolbar
。
然后设置app:contentInsetStart="0dp"
。
此属性删除左侧的边距。
然后使用您喜欢的布局自定义工具栏。
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:contentInsetEnd="0dp"
app:contentInsetStart="0dp" >
//Put here your layout.
</android.support.v7.widget.Toolbar>
在您的活动中:
Toolbar actionBar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(actionBar);
BTW我建议您遵循材料指南。 Android不会将操作栏中的图像用作IOS。
