android 清单中的小改动导致应用崩溃
Small change in android manifests is causing app to crash
很简单，我正在更改 android 清单以删除标题栏。在 styles.xml 文件中，我更改了应用程序样式 parent，在 android 清单中，我相应地更改了 android:theme。但是现在，当我在我的 android 上进行测试时，它只是进入白屏。
我的styles.xml：
<resources>
<!-- Base application theme. -->
<style name="AppTheme"
parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
我的android_manifests：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ali.colormatch2">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@android:style/Theme.Light.NoTitleBar.Fullscreen">
<activity android:name=".MainActivity"
android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ColorMatch2"
android:screenOrientation="portrait">
</activity>
<activity android:name=".LoseScreen"
android:screenOrientation="portrait">
</activity>
</application>
</manifest>
我的 MainActivity.java，这可能无关紧要，但以防万一它是罪魁祸首：
package com.example.ali.colormatch2;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onSplashPageClick(View view){
Intent intent = new Intent(MainActivity.this, ColorMatch2.class);
startActivity(intent);
}
public void onQuitClick(View view){
finish();
}
}
对应activity_main.xml：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#005825"
tools:context="com.example.ali.colormatch2.MainActivity"
android:onClick="onSplashPageClick"
android:baselineAligned="false">
<!--<Button
android:text="Button"
android:layout_width="159dp"
android:layout_height="100dp"
android:id="@+id/button5"
android:onClick="sendMessage" />
-->
<Button
android:layout_width="35dp"
android:layout_height="35dp"
android:id="@+id/button"
android:background="@android:drawable/btn_dialog"
android:onClick="onQuitClick"
android:layout_marginTop="16dp"
android:layout_marginLeft="24dp"
android:layout_marginStart="24dp"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
<TextView
android:text="Click anywhere to play"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/textView5"
android:textSize="30dp"
android:textColor="#000000"
android:layout_marginBottom="171dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fontFamily="sans-serif-thin"
android:text="Color Match"
android:gravity="center"
android:textColor="#440027"
android:textSize="75dp"
android:id="@+id/textView"
android:layout_marginBottom="12dp"
android:layout_above="@+id/textView5"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
另外需要注意的是我也试过了android:theme="@android:style/Theme.Light.NoTitleBar">
在 android 清单中，但这似乎也没有用。谢谢
