1、原来是将editview放到了popupwindow，发现editview原有的复制、粘贴、全选、选择功能失效了，所以便用dialogfragment代替了popupwindow

直接上代码

①、先看布局文件

<?xml version="." encoding="utf-"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="bottom"
android:orientation="vertical">
<linearlayout
android:id="@+id/ll_background_dialog"
android:layout_width="match_parent"
android:layout_height="dp"
android:layout_weight=""
android:background="#"
android:alpha="."
android:orientation="horizontal">
</linearlayout>
<scrollview
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/white">
<linearlayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffcdcdcd"
android:orientation="vertical">
<relativelayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<imageview
android:id="@+id/iv_quxiao_popup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="dp"
android:src="@drawable/popup_comment_no" />
<textview
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerinparent="true"
android:text="发言"
android:textcolor="#"
android:textsize="sp" />
<imageview
android:id="@+id/iv_write_popup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignparentend="true"
android:layout_alignparentright="true"
android:padding="dp"
android:src="@drawable/popup_commnet_ok" />
</relativelayout>
<edittext
android:id="@+id/et_comment_popup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="dp"
android:background="#ffffff"
android:gravity="top"
android:hint="在这里留言"
android:minlines="" />
<relativelayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginbottom="dp"
android:layout_marginleft="dp"
android:layout_marginright="dp">
<textview
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignparentright="true"
android:text="文明上网"
android:textsize="sp" />
</relativelayout>
</linearlayout>
</scrollview>
</linearlayout>

②、看自定义diaglogfragment的代码

import android.annotation.suppresslint;
import android.content.context;
import android.graphics.color;
import android.graphics.drawable.colordrawable;
import android.os.bundle;
import android.app.fragment;
import android.support.v.app.dialogfragment;
import android.view.layoutinflater;
import android.view.view;
import android.view.viewgroup;
import android.view.windowmanager;
import android.view.inputmethod.inputmethodmanager;
import android.widget.edittext;
import android.widget.imageview;
import android.widget.linearlayout;
import android.widget.toast;
import com.android.volley.authfailureerror;
import com.android.volley.request;
import com.android.volley.response;
import com.android.volley.volleyerror;
import com.android.volley.toolbox.stringrequest;
import org.json.jsonexception;
import org.json.jsonobject;
import java.util.hashmap;
import java.util.map;
import newairtek.com.app.appapplication;
import newairtek.com.sdnewsandroid.r;
import newairtek.com.url.sdnewsurl;
/**
* a simple {@link fragment} subclass.
*/
@suppresslint("validfragment")
public class customdialogfragment extends dialogfragment {
private imageview iv_quxiao_popup;//取消按钮
private imageview iv_write_popup; //确认按钮
private edittext et_comment_popup;//评论内容
private linearlayout ll_background_dialog;//容器
private boolean iscommenting = false;
private string uid;
private string id;
private string cid;
public customdialogfragment(string uid, string id, string cid) {
this.uid = uid;
this.id = id;
this.cid = cid;
}
@override
public void oncreate(bundle savedinstancestate) {
super.oncreate(savedinstancestate);
//这句代码的意思是让dialogfragment弹出时沾满全屏
setstyle(dialogfragment.style_normal, android.r.style.theme_holo_light_dialogwhenlarge_noactionbar);
}
@override
public view oncreateview(layoutinflater inflater, viewgroup container,
bundle savedinstancestate) {
view view = inflater.inflate(r.layout.popup_write_comment, null);
//让dialogfragment的背景为透明
getdialog().getwindow().setbackgrounddrawable(new colordrawable(color.transparent));
initview(view);
initevent();
return view;
}
//初始化view
private void initview(view view) {
iv_quxiao_popup = (imageview) view.findviewbyid(r.id.iv_quxiao_popup);
iv_write_popup = (imageview) view.findviewbyid(r.id.iv_write_popup);
et_comment_popup = (edittext) view.findviewbyid(r.id.et_comment_popup);
ll_background_dialog = (linearlayout) view.findviewbyid(r.id.ll_background_dialog);
}
private void initevent(){
//取消
iv_quxiao_popup.setonclicklistener(new view.onclicklistener() {
@override
public void onclick(view view) {
dismiss();
}
});
//确认发送
iv_write_popup.setonclicklistener(new view.onclicklistener() {
@override
public void onclick(view view) {
if (et_comment_popup.gettext().tostring().length() > ) {
if (!iscommenting) {
iscommenting = true;
} else {
toast.maketext(getactivity(), "正在评论，请勿重复操作", toast.length_long).show();
}
} else {
toast.maketext(getactivity(), "内容不能为空", toast.length_short).show();
}
}
});
ll_background_dialog.setonclicklistener(new view.onclicklistener() {
@override
public void onclick(view view) {
dismiss();
}
});
}
}

3、如何使用

fragmentmanager manager = getsupportfragmentmanager();//区分是v的fragment还是app包里面的
customdialogfragment dialogfragment = new customdialogfragment(uid, id, cid);
dialogfragment.show(manager, "custom");

效果图
