### 解决 ###

#### 检查是否存在该组件 ####

1.  检查xml（对于静态布局）或Java（对于动态布局）， 确保存在id名为tv\_page ，属性为TextView的组件。

#### 检查是否存在组件覆盖 ####

1.  检查是否存在组件覆盖， 对于本错误， 笔者由于marge值设置较小， 导致组件冲突， 适当增大marge值即可。

android:layout_marginRight = 20dp

改为

android:layout_marginRight = 100dp

### 原因 ###

由错误Could not find method onClick(View) in a parent or ancestor Context for android:onClick attribute defined on view class androidx.appcompat.widget.AppCompatTextView with id 'tv\_page’可知程序无法找到 ‘tv\_page’， 对于已经设置的组件若后续组件在占据该组件位置， 将会导致该组件被覆盖， 即不可见
