我遇到問題。我有一個支持行動欄,我在其中設置了一個圖像。問題是圖像稍微偏右。我認爲這是一個兼容性問題。AppCompat SupportActionBar有關圖像放置的問題
這裏是圖像的截圖:
正如你所看到的,在動作條的圖像稍微向右(如果它是不可見的,相信我,它是)。
圖像最初正確居中,當我使用actionBar時,但是當我將appcompat添加到項目時,getActionBar()開始返回null,並且應用程序崩潰。我搜索了互聯網並得到了getSupportActionBar()方法。這次應用程序沒有崩潰,但圖像沒有像以前那樣正確居中。我懷疑這是一個主題/兼容性/重寫或類似的事情。
任何人都可以幫助我嗎?
下面是其中i的調用操作欄中的方法:
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);
}
這裏是 「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>
這裏是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
}
}
而且這裏的風格:
種風格:
<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. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
<color name="azure">#50aaf1</color>
<color name="black">#302D2D</color>
<color name="white">#ffffff</color>
V11 /:
<resources>
<!--
Base application theme for API 11+. This theme completely replaces
AppBaseTheme from res/values/styles.xml on API 11+ devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
<!-- API 11 theme customizations can go here. -->
</style>
V14 /:
<resources>
<!--
Base application theme for API 14+. This theme completely replaces
AppBaseTheme from BOTH res/values/styles.xml and
res/values-v11/styles.xml on API 14+ devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- API 14 theme customizations can go here. -->
</style>
有人可以善待我嗎? 乾杯!
您可以發佈您在操作欄中設置的圖片照片嗎?因爲我想檢查實際的照片,代碼似乎是正確的,所以可能有圖像本身的問題,所以請編輯您的問題,並添加實際圖像 – Apurva 2015-02-07 10:07:16
