Question

将应用迁移到Android X应用后，运行时崩溃。当“片段的活动”使布局膨胀时会发生这种情况。我的StackTrace是：

经过一些调试后，我发现在迁移之前项目使用material-components-android时会发生问题，并且某些操作必须手动完成：

TextInputLayout 子视图应为 com.google.android.material.textfield.TextInputEditText 而不是EditText或AppCompatEditText：

<com.google.android.material.textfield.TextInputLayout
            android:id="@+id/input_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <com.google.android.material.textfield.TextInputEditText
                android:id="@+id/edit_text"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>

TextInputLayout 应该使用从 Widget.MaterialComponents.TextInputLayout.FilledBox <继承的 android：theme 和 app：errorTextAppearance / strong>

styles.xml：

<style name="TextInputLayoutStyle" parent="Widget.MaterialComponents.TextInputLayout.FilledBox"> ... </style> <style name="TextInputLayoutErrorAppearance" parent="Widget.MaterialComponents.TextInputLayout.FilledBox"> ... </style>

layout.xml

<com.google.android.material.textfield.TextInputLayout android:id="@+id/input_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/TextInputLayoutStyle" app:errorEnabled="true" app:errorTextAppearance="@style/TextInputLayoutErrorAppearance"> <com.google.android.material.textfield.TextInputEditText android:id="@+id/edit_text" android:layout_width="match_parent" android:layout_height="wrap_content"/> </com.google.android.material.textfield.TextInputLayout>

如果要切换密码输入类型，则必须将 app：passwordToggleEnabled 和 app：passwordToggleTint 替换为 app：endIconMode =“ password_toggle” < / strong>

<com.google.android.material.textfield.TextInputLayout android:id="@+id/password_input_layout" android:layout_width="match_parent" android:layout_height="wrap_content" app:errorEnabled="true" app:endIconMode="password_toggle"> <com.google.android.material.textfield.TextInputEditText android:id="@+id/password_edit_text" android:layout_width="match_parent" android:layout_height="wrap_content" android:inputType="textPassword"/>

迁移到Android X应用后，崩溃了android.view.InflateException
