Android--解決EditText放到popupWindow中，原有複製、粘貼、全選、選擇功能失效問題

1、原來是將EditView放到了popupwindow，發現EditView原有的複製、粘貼、全選、選擇功能失效了，所以便用DialogFragment代替了popupWindow

直接上代碼

①、先看佈局文件

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 3     android:layout_width="match_parent"
 4     android:layout_height="match_parent"
 5     android:gravity="bottom"
 6     android:orientation="vertical">
 7     <LinearLayout
 8         android:id="@+id/ll_background_dialog"
 9         android:layout_width="match_parent"
10         android:layout_height="0dp"
11         android:layout_weight="1"
12         android:background="#000"
13         android:alpha="0.7"
14         android:orientation="horizontal">
15 
16     </LinearLayout>
17     <ScrollView
18         android:layout_width="match_parent"
19         android:layout_height="wrap_content"
20         android:background="@android:color/white">
21 
22         <LinearLayout
23             android:layout_width="match_parent"
24             android:layout_height="wrap_content"

28             <RelativeLayout
29                 android:layout_width="match_parent"
30                 android:layout_height="wrap_content">
31 
32                 <ImageView
33                     android:id="@+id/iv_quxiao_popup"
34                     android:layout_width="wrap_content"
35                     android:layout_height="wrap_content"
36                     android:padding="16dp"
37                     android:src="@drawable/popup_comment_no" />
38 
39                 <TextView
40                     android:layout_width="wrap_content"
41                     android:layout_height="wrap_content"
42                     android:layout_centerInParent="true"
43                     android:text="發言"
44                     android:textColor="#000"
45                     android:textSize="16sp" />
46 
47                 <ImageView
48                     android:id="@+id/iv_write_popup"
49                     android:layout_width="wrap_content"
50                     android:layout_height="wrap_content"
51                     android:layout_alignParentEnd="true"
52                     android:layout_alignParentRight="true"
53                     android:padding="16dp"
54                     android:src="@drawable/popup_commnet_ok" />
55             </RelativeLayout>
56 
57             <EditText
58                 android:id="@+id/et_comment_popup"
59                 android:layout_width="match_parent"
60                 android:layout_height="wrap_content"
61                 android:layout_margin="16dp"
62                 android:background="#ffffff"
63                 android:gravity="top"
64                 android:hint="在這裡留言"
65                 android:minLines="3" />
66 
67             <RelativeLayout
68                 android:layout_width="match_parent"
69                 android:layout_height="wrap_content"
70                 android:layout_marginBottom="16dp"
71                 android:layout_marginLeft="16dp"
72                 android:layout_marginRight="16dp">
73 
74                 <TextView
75                     android:layout_width="wrap_content"
76                     android:layout_height="wrap_content"

78                     android:text="文明上網"
79                     android:textSize="12sp" />
80             </RelativeLayout>
81         </LinearLayout>
82 
83     </ScrollView>
84 
85 </LinearLayout>

②、看自定義diaglogFragment的代碼

  1 import android.annotation.SuppressLint;
  2 import android.content.Context;
  3 import android.graphics.Color;
  4 import android.graphics.drawable.ColorDrawable;
  5 import android.os.Bundle;
  6 import android.app.Fragment;
  7 import android.support.v4.app.DialogFragment;
  8 import android.view.LayoutInflater;
  9 import android.view.View;
 10 import android.view.ViewGroup;
 11 import android.view.WindowManager;
 12 import android.view.inputmethod.InputMethodManager;
 13 import android.widget.EditText;
 14 import android.widget.ImageView;
 15 import android.widget.LinearLayout;
 16 import android.widget.Toast;
 17 
 18 import com.android.volley.AuthFailureError;
 19 import com.android.volley.Request;
 20 import com.android.volley.Response;
 21 import com.android.volley.VolleyError;
 22 import com.android.volley.toolbox.StringRequest;
 23 
 24 import org.json.JSONException;
 25 import org.json.JSONObject;
 26 
 27 import java.util.HashMap;
 28 import java.util.Map;
 29 
 30 import newairtek.com.app.AppApplication;
 31 import newairtek.com.sdnewsandroid.R;
 32 import newairtek.com.url.SdNewsUrl;
 33 
 34 /**
 35  * A simple {@link Fragment} subclass.
 36  */
 37 @SuppressLint("ValidFragment")
 38 public class CustomDialogFragment extends DialogFragment {
 39 
 40     private ImageView iv_quxiao_popup;//取消按鈕
 41     private ImageView iv_write_popup; //確認按鈕
 42     private EditText et_comment_popup;//評論內容
 43     private LinearLayout ll_background_dialog;//容器
 44 
 45     private boolean isCommenting = false;
 46 
 47     private String uid;
 48     private String id;
 49     private String cid;
 50 
 51     public CustomDialogFragment(String uid, String id, String cid) {
 52         this.uid = uid;
 53         this.id = id;
 54         this.cid = cid;
 55     }
 56 
 57     @Override
 58     public void onCreate(Bundle savedInstanceState) {
 59         super.onCreate(savedInstanceState);
 60         //這句代碼的意思是讓dialogFragment彈出時沾滿全屏
 61         setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Holo_Light_DialogWhenLarge_NoActionBar);
 62     }
 63 
 64     @Override
 65     public View onCreateView(LayoutInflater inflater, ViewGroup container,
 66                              Bundle savedInstanceState) {
 67         View view = inflater.inflate(R.layout.popup_write_comment, null);
 68         //讓DialogFragment的背景為透明
 69         getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
 70         initView(view);
 71         initEvent();
 72         return view;
 73     }
 74 
 75     //初始化view
 76     private void initView(View view) {
 77         iv_quxiao_popup = (ImageView) view.findViewById(R.id.iv_quxiao_popup);
 78         iv_write_popup = (ImageView) view.findViewById(R.id.iv_write_popup);
 79         et_comment_popup = (EditText) view.findViewById(R.id.et_comment_popup);
 80         ll_background_dialog = (LinearLayout) view.findViewById(R.id.ll_background_dialog);
 81     }
 82 
 83     private void initEvent(){
 84         //取消
 85         iv_quxiao_popup.setOnClickListener(new View.OnClickListener() {
 86             @Override
 87             public void onClick(View view) {
 88                 dismiss();
 89             }
 90         });
 91         //確認發送
 92         iv_write_popup.setOnClickListener(new View.OnClickListener() {
 93             @Override
 94             public void onClick(View view) {
 95                 if (et_comment_popup.getText().toString().length() > 1) {
 96                     if (!isCommenting) {
 97                         isCommenting = true;
 98                         
 99                     } else {
100                         Toast.makeText(getActivity(), "正在評論，請勿重覆操作", Toast.LENGTH_LONG).show();
101                     }
102                 } else {
103                     Toast.makeText(getActivity(), "內容不能為空", Toast.LENGTH_SHORT).show();
104                 }
105             }
106         });
107         ll_background_dialog.setOnClickListener(new View.OnClickListener() {
108             @Override
109             public void onClick(View view) {
110                 dismiss();
111             }
112         });
113     }
114 
115     
116 
117    
118 
119 }

3、如何使用

1 FragmentManager manager = getSupportFragmentManager();//區分是v4的Fragment還是app包裡面的
2                     CustomDialogFragment dialogFragment = new CustomDialogFragment(uid, id, cid);
3                     dialogFragment.show(manager, "custom");
