实现QQ上传图片

版权声明：com.anleiya.www https://blog.csdn.net/weixin_42996187/article/details/82826731

1.导入依赖
implementation ‘de.hdodenhof:circleimageview:2.2.0’
implementation ‘org.xutils:xutils:3.3.40’

2…首先创建一个初始化类

package com.example.gone_05;

import android.app.Application;
import org.xutils.x;

public class App extends Application {

@Override
public void onCreate() {
    super.onCreate();
    x.Ext.init(this);
}

}
3.布局页面

<de.hdodenhof.circleimageview.CircleImageView
android:id="@+id/mHeader_iv"
android:layout_width=“200dp”
android:layout_height=“200dp”
android:layout_gravity=“center_horizontal”
android:layout_marginTop=“50dp”
android:src="#E4E3E3" />
<android.support.v4.widget.Space
android:layout_width=“match_parent”
android:layout_height=“0dp”
android:layout_weight=“1”/>

5.最后一步别忘了加权限

6.最后一步就是清单文件配置声明创建的APP类
android:name=".App"
