我在Figma上设计了一个应用程序，并通过使用Android Studio的扩展获得了资产。之后，我使用API 33从Android Studio创建了一个"无活动"。
无论如何，Figma插件是"导出工具包"创建了一个zip文件。它包含一个java文件夹，一个res文件夹和"AndroidManifest.xml"。当我打开项目并按照"res〉layout〉login_page_activity.xml"，它作为布局出现在右侧面板。但当我用模拟器运行应用程序时;应用程序建立，但在启动过程后，它突然停止，并有一个崩溃像"Weesi保持停止"。我不能得到我在figma上设计的视图。有人能帮忙吗？我分享代码和截图。

"登录页面活动"的代码;*

package exportkit.figma;

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

import android.view.View;
import android.widget.ImageView;

public class login_page_activity extends Activity {

    
    private View _bg__login_page;
    private ImageView vector;
    private ImageView vector_ek1;
    private ImageView vector_ek2;
    private ImageView vector_ek3;

    private View rectangle_1;
    private ImageView mask_group;
    private ImageView vector_ek7;
    private ImageView mask_group_ek1;
    private ImageView vector_ek8;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.login_page);

        
        _bg__login_page = (View) findViewById(R.id._bg__login_page);
        vector = (ImageView) findViewById(R.id.vector);
        vector_ek1 = (ImageView) findViewById(R.id.vector_ek1);
        vector_ek2 = (ImageView) findViewById(R.id.vector_ek2);
        vector_ek3 = (ImageView) findViewById(R.id.vector_ek3);
        vector_ek4 = (ImageView) findViewById(R.id.vector_ek4);
        vector_ek5 = (ImageView) findViewById(R.id.vector_ek5);
        vector_ek6 = (ImageView) findViewById(R.id.vector_ek6);
        rectangle_1 = (View) findViewById(R.id.rectangle_1);
        mask_group = (ImageView) findViewById(R.id.mask_group);
        vector_ek7 = (ImageView) findViewById(R.id.vector_ek7);
        mask_group_ek1 = (ImageView) findViewById(R.id.mask_group_ek1);
        vector_ek8 = (ImageView) findViewById(R.id.vector_ek8);
    
        
        //custom code goes here
    
    }
}

- 这种用法会产生错误，所以我添加了以下包;**

import "com.example.weesi.R";

- 它解决。但在这种情况下的大问题是，当我点击运行模拟器，它给出的错误是在图片中;**

- 这是logcat错误。**

试试这个代码，

<activity
    android:name="com.example.weesi.login_page_activity"
    android:configChanges="orientation|keyboardHidden|screenSize"
    android:label="@string/app_name"
    android:exported="true"  >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

更新清单中的活动标记。

我认为您没有在AndroidManifest.xml中注册Activity
请将您的Activity添加到您的AndroidManifest.xml

您应该将您的活动添加到“AndroidManifest.xml”文件中。

<activity
android:name="YOUR_ACTIVITY"
android:exported="true"  >
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
    <meta-data
            android:name="android.app.lib_name"
            android:value="" />
</activity>

然后再次运行应用程序。然后您的问题将得到解决！
