问题：PopupWindow中，EditText无法使用复制粘贴功能。
方法：使用DialogFragment实现。
package com.example.administrator.dialogfragmentdemo; import android.content.Context; import android.content.DialogInterface; import android.graphics.drawable.BitmapDrawable; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v4.app.DialogFragment; import android.text.TextUtils; import android.view.Gravity; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.view.Window; import android.view.WindowManager; import android.view.inputmethod.InputMethodManager; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; /** * Created by qhm on 2018/10/29. * Blog : https://blog.csdn.net/qq_37077360 * * DialogFragment取代PopupWindow，解决PopupWindow中EditText无法复制粘贴问题 */ public class EditDialog extends DialogFragment { private View mLayout; Context mContext; private EditText et_content; CommonInterface listener; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //设置样式、传值等。 // setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Holo_Light_DialogWhenLarge_NoActionBar); setStyle(STYLE_NO_TITLE, R.style.dialog_edit); } @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { this.mContext = getActivity(); mLayout = inflater.inflate(R.layout.pop_send_comment, container); et_content = (EditText) mLayout.findViewById(R.id.et_content); TextView tv_send=(TextView) mLayout.findViewById(R.id.tv_send) ;//我知道了 final Window window = getDialog().getWindow(); //设置dialog的位置 window.setGravity(Gravity.BOTTOM); //去除白色背景【必须设置，否则宽高设置等可能不生效】。style中已通过windowBackground设置 // window.setBackgroundDrawable(new BitmapDrawable()); //去除原来的标题。style中已通过windowNoTitle设置 // getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE); // 自动显示软键盘。【方法一】 getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE); getDialog().setOnShowListener(new DialogInterface.OnShowListener() { @Override public void onShow(DialogInterface dialog) { //设置宽度占满全屏。必须在show()之后设置，此处已监听show()；或者在其生命周期onstart()或者onResume()中设置 WindowManager.LayoutParams attributes = window.getAttributes(); attributes.width= ViewGroup.LayoutParams.MATCH_PARENT; window.setAttributes(attributes); // //获取焦点，并自动弹出键盘【方法二】 // InputMethodManager inputmanger = (InputMethodManager) mContext // .getSystemService(Context.INPUT_METHOD_SERVICE); // inputmanger.showSoftInput(et_content, 0); } }); //设置外部点击可以取消 getDialog().setCancelable(true); getDialog().setCanceledOnTouchOutside(true); tv_send.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { if(TextUtils.isEmpty(et_content.getText().toString())){ Toast.makeText(mContext,"说点什么吧",Toast.LENGTH_SHORT).show(); return; } // dismiss(); //调用接口发表评论。当后台返回success，再调用dismiss()关闭 if (listener!=null){ listener.operate(et_content.getText().toString().trim()); } } }); return mLayout; } public void setOnSendingListener(CommonInterface listener){ this.listener=listener; } }
style.xml文件：
<style name="dialog_edit" parent="Theme.AppCompat.Light.Dialog.Alert"> <item name="android:windowSoftInputMode">adjustPan</item> <!-- 是否有边框 --> <item name="android:windowFrame">@null</item> <!--标题 --> <item name="android:windowNoTitle">true</item> <!--阴影 --> <item name="android:windowIsTranslucent">false</item><!--半透明--> <!-- 点外边可以消失 --> <item name="android:windowCloseOnTouchOutside">true</item> <item name="android:windowBackground">@null</item> </style>最终使用：
dialog = new EditDialog(); dialog.setOnSendingListener(new CommonInterface() { @Override public void operate(Object object) { //todo 保存评论,成功则关闭对话框 if (1==1)//测试 dialog.dismiss(); } }); FragmentManager fm=getSupportFragmentManager(); dialog.show(fm,"tag");
