Question

在the answer here之后，我尝试检查是否选择了某个微调文本。微调器出现在对话框中，所以我尝试了：

onView(withId(R.id.package_spinner)).inRoot(isDialog()).check(matches(withSpinnerText(containsString("sachet"))));

但是这不起作用，我收到以下错误消息：

android.support.test.espresso.base.DefaultFailureHandler $ AssertionFailedWithCauseError： 'with text：包含“sachet”的字符串与所选的字符串不匹配视图。预期：带文字：包含“香包”的字符串得到：“AppCompatSpinner {id = 2131624039，res-name = package_spinner，visibility = VISIBLE，width = 620，height = 75，has-focus = false， has-focusable = true，has-window-focus = true，is-clickable = true， is-enabled = true，is-focused = false，is-focusable = true， is-layout-requested = false，is-selected = false， root-is-layout-requested = false，has-input-connection = false，x = 0.0， y = 75.0，child-count = 1}“

“is-selected = false”是否意味着它找不到的微调器？这是在使用API 18的真实设备（非仿真器）上运行。在Espresso运行期间以及手动测试时，微调器正确设置为“sachet”。为什么Espresso有问题？

不确定这是否相关，但是微调器适用于以下类型的对象：

public class PackageType {
    private int id;
    private String name;

    private final Context ctx;

    public PackageType(Context context) { this.ctx=context; }
    public PackageType(String name, Context context) {
        super();
        this.ctx = context;
        setName(name);
    }

    // setters
    public void setId(int i) { this.id = i; }
    public void setName(String u) {
        this.name = u;
    }


    // getters
    public int getId() { return id; }
    public String getName() { return name; }
}

并且微调器适配器看起来像：

class SpinnerPackageTypeAdapter extends ArrayAdapter<PackageType> {
    private final List<PackageType> packageTypes;
    private final Context mContext;

    public SpinnerPackageTypeAdapter(Context context, int resource, List<PackageType> packageTypes) {
        super(context, resource, packageTypes);
        this.mContext = context;
        this.packageTypes = packageTypes;
    }

    public PackageType getItem(int position) { return packageTypes.get(position); }

    public long getItemId(int position) { return position; }

    // this is for the passive state of the spinner
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // use dynamically created TextView, but could reference custom layout
        TextView label = new TextView(mContext);
        label.setTextColor(Color.BLACK);
        label.setTextSize(mContext.getResources().getDimension(R.dimen.list_row_font_size));
        label.setGravity(Gravity.CENTER);
        label.setText(getItem(position).getName());

        return label;
    }

    // this is for the chooser dropped down spinner
    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        TextView label = (TextView) View.inflate(mContext,R.layout.row_spinner,null);
        label.setText(getItem(position).getName());
        return label;
    }

}

我发现了问题。在类PackageType中，我必须覆盖toString（）方法（当然，只要“name”在其中，其他版本就可以）：

@Override
    public String toString() {
        return "PackageType [id=" + id + ", name=" + name + "]";
    }

Espresso匹配选定的微调文本
