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");
