我正在尝试使用Material Theme为我的应用添加导航抽屉。关注this tutorial here to start。
输出应该看起来像this GIF:
看起来 AppCompatActivity与android:Theme.Material 不兼容,不明白为什么?
我的res/styles.xml
:
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
</style>
<!-- your theme inherits from the material theme -->
<style name="MaterialTheme" parent="android:Theme.Material">
<!-- theme customizations -->
</style>
我的活动代码,只是扩展AppCompatActivity
:
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
setContentView(R.layout.mainactivity);
......
现在,我的清单,不是我想要使用的:MaterialTheme
:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.xxxx.xxxxxxxx.xxx" >
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/MaterialTheme" >
<activity
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
这是我得到的错误:

答案 0 :(得分:1)
看起来AppCompatActivity与android:Theme.Material不兼容,不明白为什么?
appcompat-v7
操作栏后退需要使用Theme.AppCompat
及其子主题(例如Theme.AppCompat.Light
)。那就是那个图书馆的本质。您的选择是:
不使用AppCompatActivity
并使用原生操作栏或
不使用Theme.Material
而是使用Theme.AppCompat
