Android--解决EditText放到popupWindow中，原有复制、粘贴、全选、选择功能失效问题

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="1.0" encoding="utf-8"?>
 <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="0dp"
         android:layout_weight="1"
         android:background="#000"
         android:alpha="0.7"
         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="16dp"
                     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="#000"
                     android:textSize="16sp" />

                 <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="16dp"
                     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="16dp"
                 android:background="#ffffff"
                 android:gravity="top"
                 android:hint="在这里留言"
                 android:minLines="3" />

             <RelativeLayout
                 android:layout_width="match_parent"
                 android:layout_height="wrap_content"
                 android:layout_marginBottom="16dp"
                 android:layout_marginLeft="16dp"
                 android:layout_marginRight="16dp">

                 <TextView
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     android:layout_alignParentRight="true"
                     android:text="文明上网"
                     android:textSize="12sp" />
             </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.v4.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() > 1) {
                     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v4的Fragment还是app包里面的
                     CustomDialogFragment dialogFragment = new CustomDialogFragment(uid, id, cid);
                     dialogFragment.show(manager, "custom");
