增加按钮的可点击区域 [英] Increase the clickable area of the button

问题描述

我想增加按钮的可点击区域。但是按钮中的图像应保持相同大小。我也将图像设置为背景而不是背景。

I want to increase the clickable area of the button.But the image in the button should remain of same size.Also i have set image as a background not as source .How can i do that?

 <Button
        android:id="@+id/backbutton"
        android:layout_width="25dp"
        android:layout_height="25dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="15dp"
        android:layout_marginTop="5dp"
        android:background="@drawable/arrow"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"

        android:textColor="@color/title_gray"
        android:textSize="14sp"


        android:visibility="visible" />

推荐答案

只需将按钮的父级布局（较大大小或可点击大小），然后执行类似的点击事件-

Just make the parent layout of the button (of larger size or clickable size), and perform click event of that like -

<LinearLayout
 android:id="@+id/backbuttonlayout"
        android:layout_width="50dp"
        android:layout_height="50dp">
<Button
        android:id="@+id/backbutton"
        android:layout_width="25dp"
        android:layout_height="25dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="15dp"
        android:layout_marginTop="5dp"
        android:background="@drawable/arrow"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"

        android:textColor="@color/title_gray"
        android:textSize="14sp"


        android:visibility="visible" />
</LinearLayout>

现在，在您的活动中，执行--

Now, inside your activity, do like -

LinearLayout backbuttonlayout = (LinearLayout)findViewById(R.id.backbuttonlayout);

并在backbuttonlayout上执行setOnClickListener（）

and perform setOnClickListener() on backbuttonlayout
