使EditText可点击

Question

Good evening, i have the following layout and i would like to make the Edit Text clickable everywhere. Also if layout_height is set to match_parent, the Edit Text clickable area works like wrap_content.

This is the layout.

<?xml version="1.0" encoding="utf-8"?>

    <RelativeLayout 
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"  
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:focusable="true"
        android:focusableInTouchMode="true">

    <include
        android:id="@+id/toolbar"
        layout="@layout/toolbar"/>

     <RelativeLayout
         android:id="@+id/relative"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_below="@+id/toolbar">   

    <TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingLeft="20dp"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:paddingRight="20dp">        

    <EditText 
        android:id="@+id/title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    </TextInputLayout>
    </RelativeLayout>

    <ScrollView    
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/relative">

     <RelativeLayout
         android:layout_width="wrap_content"
         android:layout_height="wrap_content">  

    <TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="20dp"
        android:layout_marginLeft="20dp"
        android:layout_marginEnd="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="10dp">     

    <EditText
        android:id="@+id/content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:hint="@string/note_content"
        android:background="@null"      
        android:gravity="top"/>     

    </TextInputLayout>
    </RelativeLayout> 
    </ScrollView>

    </RelativeLayout>

How can i make the Edit Text clickable everywhere in the Relative Layout inside the Scroll View?

Answer 1

While I don't understand why you are wanting to do this, you could make an button with the invisible property set to true, that covers the entire layout. Then respond when user touches this invisible button.

You respond by using the EditText method called setOnEditorActionListener()

See the info on this page with the heading "Responding to action button events": http://developer.android.com/guide/topics/ui/controls/text.html

Answer 2

In a scrollView you can't fill the entire view until there is content here, you are asking to make the EditText Fill the whole parent space left apart from the TextView so that you can click any part of the layout to focus on the EditText . Except you give the EditText a layout_height it will remain wrap since the layout is in the RelativeLayout' which is a child for of the ScrollView`.
