使Intent.resolveActivity()在Roboletric测试中返回true

import android.content.Intent;
import android.content.pm.PackageManager;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;
import org.robolectric.shadows.ShadowPackageManager;

@RunWith(RobolectricTestRunner.class)
@Config(manifest = Config.NONE)
public class MyTest {

    @Test
    public void testResolveActivity() {
        // 创建一个模拟的PackageManager对象
        ShadowPackageManager shadowPackageManager = new ShadowPackageManager();

        // 设置resolveActivity()返回true的条件
        shadowPackageManager.setResolveActivity(true);

        // 获取PackageManager的实例
        PackageManager packageManager = shadowPackageManager.getPackageManager();

        // 创建一个Intent对象
        Intent intent = new Intent();

        // 调用resolveActivity()方法，判断是否有能够处理该Intent的Activity
        boolean resolved = intent.resolveActivity(packageManager) != null;

        // 断言resolved为true
        assert resolved;
    }
