android - 无法启动活动组件信息 java.lang.RuntimeException：

问题描述

我正在尝试开发一个android应用程序。有一个java.lang.RuntimeException. 我在描述和 XML 文件中创建了一个 Java 类代码。我已将活动设置为在运行时显示，但它显示很遗憾，应用程序已关闭。这可能是什么问题？

我的 XML 文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:tools="http://schemas.android.com/tools"
    android:background="@drawable/welcome">

    <ImageView
        android:id="@+id/app_logo"

        android:layout_height="100dp"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="60dp"
        android:src="@drawable/ntuuma_logo"
        android:contentDescription="@string/todo" />

    <Button
        android:id="@+id/main_join_now_btn"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_above="@+id/main_login_btn"
        android:layout_marginBottom="5dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:background="@drawable/input_design"
        android:padding="20dp"

        android:textSize="18sp"
        android:text="@string/join_now"
        android:textColor="@android:color/white"/>
</RelativeLayout>

我的java文件

import android.app.Activity;
import android.os.Bundle;

   public class second_Activity extends Activity {
      @Override
     protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
           setContentView(R.layout.register_activity);
   }
}

解决方案

当您将可绘制图像放在错误的文件夹中时，会发生此问题。例如，drawable-v24它在 API < 21 上崩溃。

检查您的welcome图像是否存在于可绘制文件夹中，没有任何（v-24 或 v-26）

您可以在没有任何 api 版本的情况下粘贴welcome到 drawable 中来解决问题。

右键单击welcome并单击在文件夹中显示（Linux中的文件）然后将其复制并转到上一个文件夹并找到可绘制并粘贴在其​​中。
