小编Jos*_*era的帖子

我已经使用此代码作为@gnobal发布在/sf/answers/189047841/上,它运行良好.但我的问题是,我发现当我应用Theme.Transparent时,当我旋转手机时,活动不会进入横向模式.

主题:

 <style name="Theme.Transparent" parent="android:Theme.Dialog">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>
  </style>

布局:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layoutImagen"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    android:orientation="vertical"
    android:windowContentOverlay="@null"
    android:windowNoTitle="true"
    tools:context=".ImagenExamen_activity" >

<!--     android:background="#CC000000" -->
<!--     android:backgroundDimEnabled="true" -->

    <ImageView
        android:id="@+id/imageViewImagen"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center" />

</LinearLayout>

活动:

import android.app.Activity;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;

import com.meapp.Utilities;

public class Imagen_activity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_imagen_examen);

        Bundle b = getIntent().getExtras(); …

我在我的Android应用程序中尝试了一个非常奇怪的行为,并且无法在Stackoverflow或其他任何地方找到解决方案.

我有一个Android应用程序正常工作,从Eclipse加载到手机时没有错误.但是签名后我在Logcat中看到了这个错误:

E/DatabaseUtils(2360): Writing exception to parcel

在那之后:
