如何在Android工作室制作像个人资料图片框架的个人资料图片上传框架？ [英] How to make profile picture uploder frame like Facebook profile pic frame in android studio?

问题描述

我将图像带到.xml文件，当用户从设备或图库上传图像时将显示用户配置文件，默认情况下，图像视图将是默认图像。使用Android Studio。所以请帮我解决这个问题。



我尝试过的事情：



<？xml version =1.0encoding =utf-8？>

< FrameLayout xmlns：android =http://schemas.android.com/apk/ res / android

xmlns：app =http://schemas.android.com/apk/res-auto

xmlns：tools =http：// schemas.android.com/tools

android：layout_width =match_parent

android：layout_height =match_parent

app：layout_behavior = @ string / appbar_scrolling_view_behavior

工具：context =com.example.vixcy.thecontacts.dashboard

工具：showIn =@ layout / app_bar_nav_drawer>





< TextView

android：id =@ + id / textView1

android：layout_width =300dp

android：layout_height =30dp

android：layout_marginLeft =40dp

android： layout_marginTop =300dp

android：text =TextView

android：gravity =center

android：textColor =＃000000

android：textStyle = 粗体/>



< LinearLayout

android：layout_width =200sp

android： layout_height =200sp

android：layout_marginLeft =85sp

android：layout_marginTop =50sp

android：orientation =vertical >





< ImageView

android：id =@ + id / imgView

android：layout_width =fill_parent

android：layout_height =wrap_content

android：layout_weight =10

android：adjustViewBounds =true

android：cropToPadding =true

android：elevation =10dp

android：padding = 1dp

android：scaleType =centerCrop

android：visibility =visible

app：srcCompat =@ mipmap / dummy>









<按钮

android：id =@ + id / buttonLoadPicture

= android：layout_width =wrap_contentandroid：layout_height =wrap_contentandroid：layout_gravity =centerandroid：layout_weight =0android：onclick =onClickandroid：text =Load Picture>









< TextView

android：id = @ + id / textView2

android：layout_width =300dp

android：layout_height =30dp

android：layout_marginLeft = 40dp

android：layout_marginTop =350dp

android：text =TextView

android：gravity =center

android：textColor =＃000000

android：textStyle =bold/>

解决方案

使用

 android：src =@ drawable / dummy

而不是

 app：srcCompat =@ mipmap / dummy

此外，您应该将默认图像放入可绘制文件夹，而不是mipmap文件夹。 Mipmap文件夹仅用于图标。

I take image to .xml file where user profile is going to display when user did upload image from device or gallery and by default place of image view it will be default image. using Android Studio. So please help me out of this problem.

What I have tried:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.example.vixcy.thecontacts.dashboard"
tools:showIn="@layout/app_bar_nav_drawer">


<TextView
android:id="@+id/textView1"
android:layout_width="300dp"
android:layout_height="30dp"
android:layout_marginLeft="40dp"
android:layout_marginTop="300dp"
android:text="TextView"
android:gravity="center"
android:textColor="#000000"
android:textStyle="bold"/>

<LinearLayout
android:layout_width="200sp"
android:layout_height="200sp"
android:layout_marginLeft="85sp"
android:layout_marginTop="50sp"
android:orientation="vertical">


<ImageView
android:id="@+id/imgView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="10"
android:adjustViewBounds="true"
android:cropToPadding="true"
android:elevation="10dp"
android:padding="1dp"
android:scaleType="centerCrop"
android:visibility="visible"
app:srcCompat="@mipmap/dummy">




<button
android:id="@+id/buttonLoadPicture"
="" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_weight="0" android:onclick="onClick" android:text="Load Picture">




<TextView
android:id="@+id/textView2"
android:layout_width="300dp"
android:layout_height="30dp"
android:layout_marginLeft="40dp"
android:layout_marginTop="350dp"
android:text="TextView"
android:gravity="center"
android:textColor="#000000"
android:textStyle="bold"/>

解决方案

Use

android:src="@drawable/dummy"

instead of

app:srcCompat="@mipmap/dummy"

Also, you should put the default image to drawable folder, not mipmap folder. Mipmap folder is only for icon.
