我的目标是拥有一个没有花哨功能的EditText
,只需要文本选择处理程序就可以更轻松地移动光标 - 所以没有上下文菜单或弹出窗口。
我已按照this solution消耗了ActionMode Callback事件,禁用了文本编辑功能操作栏(复制/粘贴等)的外观。
当文本存在于字段中并且文本中出现单击时,仍然会出现中间中间文本选择句柄(请参见下图)。大!我想保持这种行为。我不想要的是" PASTE"单击文本选择句柄本身时显示的菜单。
我还通过在样式XML中设置android:longClickable="false"
来禁用EditText的长按输入。禁用长按可防止"粘贴/替换"单击鼠标并保持(即长按)时出现的菜单,但是当在文本中单击鼠标(单次触摸)时,会出现文本选择手柄,当单击文本选择手柄本身时,则&# 34;粘贴"菜单选项出现(当剪贴板中有文本时)。这就是我试图阻止的。
从我从源头看到的内容,ActionPopupWindow
是弹出PASTE / REPLACE选项的内容。 ActionPopupWindow是公共类android.widget.Editor中私有抽象类HandleView中的受保护变量(mActionPopupWindow)...
如果没有禁用剪贴板服务或编辑Android源代码,有没有办法阻止它显示?我尝试为android:textSelectHandleWindowStyle
定义一种新样式,并将android:visibility
设置为gone
,但它没有效果(app会冻结一段时间,否则会显示)。

解决方案:覆盖isSuggestionsEnabled
中的canPaste
和EditText
。
对于快速解决方案,请复制下面的类 - 此类会覆盖EditText
类,并相应地阻止所有事件。
对于细节,请继续阅读。
解决方案在于防止PASTE / REPLACE菜单出现在(未记录的)android.widget.Editor
类的show()
方法中。在菜单出现之前,检查if (!canPaste && !canSuggest) return;
。用作设置这些变量的基础的两个方法都在EditText
类:
isSuggestionsEnabled()
为public,因此可能会被覆盖。canPaste()
不是,因此必须在派生类中由introducing a function of the same name隐藏。因此,将这些更新合并到一个同时具有setCustomSelectionActionModeCallback和disabled long-click的类中,这里是完整的类,可以阻止所有编辑(但仍显示text selection handler)以进行控制光标:
package com.cjbs.widgets;
import android.content.Context;
import android.util.AttributeSet;
import android.view.ActionMode;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.EditText;
/**
* This is a thin veneer over EditText, with copy/paste/spell-check removed.
*/
public class NoMenuEditText extends EditText
{
private final Context context;
/** This is a replacement method for the base TextView class' method of the same name. This
* method is used in hidden class android.widget.Editor to determine whether the PASTE/REPLACE popup
* appears when triggered from the text insertion handle. Returning false forces this window
* to never appear.
* @return false
*/
boolean canPaste()
{
return false;
}
/** This is a replacement method for the base TextView class' method of the same name. This method
* is used in hidden class android.widget.Editor to determine whether the PASTE/REPLACE popup

* @return false
*/
@Override
public boolean isSuggestionsEnabled()
{
return false;
}
public NoMenuEditText(Context context)
{
super(context);
this.context = context;
init();
}
public NoMenuEditText(Context context, AttributeSet attrs)
{
super(context, attrs);
this.context = context;
init();
}
public NoMenuEditText(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
this.context = context;
init();
}
private void init()
{
this.setCustomSelectionActionModeCallback(new ActionModeCallbackInterceptor());
this.setLongClickable(false);
}
/**
* Prevents the action bar (top horizontal bar with cut, copy, paste, etc.) from appearing
* by intercepting the callback that would cause it to be created, and returning false.
*/
private class ActionModeCallbackInterceptor implements ActionMode.Callback
{
private final String TAG = NoMenuEditText.class.getSimpleName();
public boolean onCreateActionMode(ActionMode mode, Menu menu) { return false; }
public boolean onPrepareActionMode(ActionMode mode, Menu menu) { return false; }
public boolean onActionItemClicked(ActionMode mode, MenuItem item) { return false; }
public void onDestroyActionMode(ActionMode mode) {}
}
}
我在Android v4.4.2和v4.4.3中测试了这个。

这是一个禁用&#34;粘贴&#34;弹出。您必须覆盖EditText
方法:
@Override
public int getSelectionStart() {
for (StackTraceElement element : Thread.currentThread().getStackTrace()) {
if (element.getMethodName().equals("canPaste")) {
return -1;
}
}
return super.getSelectionStart();
}
此解决方案也适用于较新版本的Android,与接受的答案不同。

当蓝色视图(插入控制器)根本没有出现时找到另一个解决方案。我使用反射来设置Editor类的目标布尔字段。查看android.widget.Editor和android.widget.TextView以获取更多详细信息。
将以下代码添加到自定义EditText中(包含本主题中的所有先前代码):
@Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
// setInsertionDisabled when user touches the view
this.setInsertionDisabled();
}
return super.onTouchEvent(event);
}
/**
* This method sets TextView#Editor#mInsertionControllerEnabled field to false
* to return false from the Editor#hasInsertionController() method to PREVENT showing
* of the insertionController from EditText
* The Editor#hasInsertionController() method is called in Editor#onTouchUpEvent(MotionEvent event) method.
*/
private void setInsertionDisabled() {
try {
Field editorField = TextView.class.getDeclaredField("mEditor");
editorField.setAccessible(true);
Object editorObject = editorField.get(this);
Class editorClass = Class.forName("android.widget.Editor");
Field mInsertionControllerEnabledField = editorClass.getDeclaredField("mInsertionControllerEnabled");
mInsertionControllerEnabledField.setAccessible(true);
mInsertionControllerEnabledField.set(editorObject, false);
}
catch (Exception ignored) {
// ignore exception here
}
}
另外,也许你可以找到比onTouch()更好的地方来调用目标方法。

我找不到隐藏菜单弹出窗口的方法,但如果用户点击菜单,您可以禁用粘贴
创建自定义EditText
并覆盖onTextContextMenuItem
方法,并为android.R.id.paste
和android.R.id.pasteAsPlainText
菜单ID返回false。
@Override
public boolean onTextContextMenuItem(int id) {
switch (id){
case android.R.id.paste:
case android.R.id.pasteAsPlainText:
return false;
}
return super.onTextContextMenuItem(id);
}

您可以通过执行以下操作完全删除menuItem:
Java:
ActionMode.Callback callback = new ActionMode.Callback() {
@Override
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
if (menu != null) {
menu.removeItem(android.R.id.paste);
}
return true;
}
@Override
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
return true;
}
@Override
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
return false;
}
@Override
public void onDestroyActionMode(ActionMode mode) {
}
};
mEditText.setCustomInsertionActionModeCallback(callback);
mEditText.setCustomSelectionActionModeCallback(callback);
科特琳:
val callback = object : ActionMode.Callback {
override fun onActionItemClicked(mode: ActionMode?, item: MenuItem?): Boolean {
return false
}
override fun onCreateActionMode(mode: ActionMode?, menu: Menu?): Boolean {
menu?.removeItem(android.R.id.paste)
return true
}
override fun onPrepareActionMode(mode: ActionMode?, menu: Menu?): Boolean {
return true
}
override fun onDestroyActionMode(mode: ActionMode?) {}
}
然后在EditText中使用站点:
fun preventPaste() {
customInsertionActionModeCallback = callback
customSelectionActionModeCallback = callback
}

Use this in java file
if (android.os.Build.VERSION.SDK_INT < 11) {
editText.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
@Override`enter code here`
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
menu.clear();
}
});
} else {
editText.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
public void onDestroyActionMode(ActionMode mode) {
// TODO Auto-generated method stub
}
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
public boolean onActionItemClicked(ActionMode mode,
MenuItem item) {
// TODO Auto-generated method stub
return false;
}`enter code here`
});
}
With this code also add android:textSelectHandle="@drawable/handle"
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<size
android:height="0dp"
android:width="0dp" />
</shape>
By Using these two combinations my problem is solved.

答案 9 :(得分:0)
以上解决方案均不适合我。我已经设法做了我的解决方案(后面的解释),它禁止在EditText上粘贴任何东西,同时保持所有其他操作有效。
主要是,您必须在EditText的实现上覆盖此方法:
@Override
public boolean onTextContextMenuItem (int id) {
if (id == android.R.id.paste) return false;
return super.onTextContextMenuItem(id);
}
因此,调查EditText代码后,在所有检查后,粘贴(以及EditText上的所有ContextMenu
操作)都发生在名为onTextContextMenuItem
的方法中:
public boolean onTextContextMenuItem(int id) {
int min = 0;
int max = mText.length();
if (isFocused()) {
final int selStart = getSelectionStart();
final int selEnd = getSelectionEnd();
min = Math.max(0, Math.min(selStart, selEnd));
max = Math.max(0, Math.max(selStart, selEnd));
}
switch (id) {
case ID_SELECT_ALL:
// This does not enter text selection mode. Text is highlighted, so that it can be
// bulk edited, like selectAllOnFocus does. Returns true even if text is empty.
selectAllText();
return true;
case ID_PASTE:
paste(min, max);
return true;
case ID_CUT:
setPrimaryClip(ClipData.newPlainText(null, getTransformedText(min, max)));
deleteText_internal(min, max);
stopSelectionActionMode();
return true;
case ID_COPY:
setPrimaryClip(ClipData.newPlainText(null, getTransformedText(min, max)));
stopSelectionActionMode();
return true;
}
return false;
}
如果您注意到,粘贴只会在id == ID_PASTE
时发生,因此,请再次查看EditText代码:
static final int ID_PASTE = android.R.id.paste;

我找到了一种简单而可靠的方法。想法是消耗触摸事件,以防止触摸事件达到下划线默认代码。
maskedEditText.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
focusAndShowKeyboard(view.getContext(), maskedEditText);
// Consume the event.
return true;
}
});
private static void focusAndShowKeyboard(Context context, EditText editText) {
editText.requestFocus();
InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
}
注意,闪烁的光标仍显示在文本末尾。只是截图无法捕捉它。

只需覆盖一个方法:

protected MovementMethod getDefaultMovementMethod() {
// we don't need arrow key, return null will also disable the copy/paste/cut pop-up menu.

我找到了一个简单的解决方案,希望可以对下面的方法扩展Edittetxt类和ovverride有所帮助。
如果您想通过比较menu.getItem(i).getTitle()
来禁用其他选项,可以采用相同的方法。
private class ActionModeCallbackInterceptor implements ActionMode.Callback
{
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
return true;
}
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
for(int i =0;i<menu.size();i++){
if(menu.getItem(i).getTitle().toString().equals("Clipboard")
|| menu.getItem(i).getTitle().toString().equals("Paste")) {
menu.getItem(i).setVisible(false);
}
}
return false;
}
public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
return false;
}
public void onDestroyActionMode(ActionMode mode) {}
}

您可以使用此代码:
if (android.os.Build.VERSION.SDK_INT < 11) {
editText.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
menu.clear();
}
});
} else {
editText.setCustomSelectionActionModeCallback(new ActionMode.Callback() {
public boolean onPrepareActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
public void onDestroyActionMode(ActionMode mode) {
// TODO Auto-generated method stub
}
public boolean onCreateActionMode(ActionMode mode, Menu menu) {
// TODO Auto-generated method stub
return false;
}
public boolean onActionItemClicked(ActionMode mode,
MenuItem item) {
// TODO Auto-generated method stub
return false;
}
});
}
从onCreateActionMode
返回false会禁用API级别大于11的剪切,复制,粘贴选项。
