Question

我创建了一个自定义视图，其中封装了TextInputLayout和TextInputEditText。该视图似乎在模拟器和硬件设备上均已正确渲染。但是，当我在Android Studio中打开预览面板时，自定义视图无法正确呈现。

以下是我收到的任何提示的错误，敬请谅解。

Couldn't resolve resource @string/path_password_strike_through
<transition> tag requires a 'drawable' attribute or child tag defining a drawable

android.view.InflateException:  Can't morph from @string/path_password_eye_mask_strike_through to @string/path_password_eye_mask_visible

已编辑（添加了代码示例）

自定义视图：



    public class MaterialTextInputView extends TextInputLayout {

      private TextInputEditText editText;

      public MaterialTextInputView(Context context) {
        super(context);
        init(context);
      }

      public MaterialTextInputView(Context context, AttributeSet) {
        super(context, attrs);

        init(context);
      }

      public MaterialTextInputView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(context);
      }

      private void init(Context context) {
        TextInputEditText editText = new TextInputEditText(getContext());
        editText.setId(ViewCompat.generateViewId());

        LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

        this.editText = editText;

        addView(this.editText, params);
        setErrorEnabled(true);
      }
    }

xml中的用法示例：

<com.marian.caloriecounter.ui.common.MaterialTextInputView
        android:id="@+id/foo"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="bar"
        style="@style/TextInputLayout"/>

确保您声明的变量未像String文件中的string/path_password_strike_through一样被解析，并且还声明了drawable文件夹中的drawable

如果没有您的代码，这将是非常模糊的...如果您分享它很容易获得帮助
