java - 膨胀 View 时出错

Question

尝试使用 Android Studio 运行我的应用程序时出现错误。
我尝试更改图像并且它正常运行，但是当我放置图像时它不会运行。

这是出错的图片:

这是我的代码布局:

这是我的 Activity :

public class AppActivity extends ActivityBase {

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

这是我得到的错误:

Answer 1

您的设备不是 hdpi，因此当 android 运行它时，它会在相应的文件夹中查找图像并崩溃，因为找不到它。你也可以

1. 将图像放入所有可绘制文件夹 ldpi、hdpi、xhdpi、mdpi、xxhdpi 和 xxxhdpi。

2. 或者，你也可以只放在“drawable”文件夹中
