Android自定义TextView不拦截父级的OnClickListener

标签： android android-layout android-linearlayout textview onclicklistener

我制作了一个自定义TextView，可以为每行文字绘制线条。

此自定义TextView与其他标准TextView和ImageView一起放置在LinearLayout中。

每当我点击普通的TextViews，ImageViews或自定义TextView外部时，点击都会被拦截。
但是，如果我单击自定义TextView，则不会截取单击。

请帮忙!!!

尝试将onFocusChanged侦听器设置为edittext。

您的意思是，当您点击自定义TextView时，您的convertView的OnClickListener没有调用onClick（）？

如果是，您可以尝试禁用自定义TextView。

<harsha.notes.view.NoteTextView android:scrollbarStyle="outsideOverlay" android:autoLink="all" android:capitalize="sentences" android:lineSpacingExtra="4.0dip"  android:text="123" android:textColor="#ff000000" android:minLines="1" android:id="@id/preview_text" android:layout_width="match_parent" android:layout_height="wrap_content" android:textSize="22dp" android:layout_marginLeft="20dp" android:layout_marginRight="25dip" android:layout_marginTop="3dip" android:layout_marginBottom="28dip" android:clickable="true"
                                    android:typeface="sans" android:visibility="visible" android:focusable="false"
                                    android:background="@android:color/transparent" android:linksClickable="true"
                                    android:focusableInTouchMode="false" android:longClickable="true"
