Make EditText ReadOnly

问题:

I want to make a read-only EditText view. The XML to do this code seems to be android:editable="false", but I want to do this in code.

How can I do this?

回答1:

Please use this code..

Edittext.setEnabled(false);

回答2:

If you setEnabled(false) then your editText would look disabled (gray, etc). You may not want to change the visual aspect of your editor.

A less intrusive way would be to use setFocusable(false).

I believe that this answers your question closer to your initial intent.

回答3:

In XML use

android:editable="false"

Example:

<EditText
android:id="@+id/EditText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:editable="false" 
/>

回答4:

This works for me:

EditText.setKeyListener(null);

回答5:

The best is by using TextView instead.

回答6:

editText.setInputType(InputType.TYPE_NULL);

As per the docs this prevents the soft keyboard from being displayed. It also prevents pasting, allows scrolling and doesn't alter the visual aspect of the view. However, this also prevents selecting and copying of the text within the view.

From my tests setting setInputType to TYPE_NULL seems to be functionally equivalent to the depreciated android:editable="false". Additionally, android:inputType="none" seems to have no noticeable effect.

回答7:

editText.setEnabled(false);
editText.setFilters(new InputFilter[] { new InputFilter() {
    public CharSequence filter(CharSequence src, int start, int end,
            Spanned dst, int dstart, int dend) {
        return src.length() < 1 ? dst.subSequence(dstart, dend) : "";
    }
} });

This will give you uneditable EditText filter. you first need to put the text you want on the editText field and then apply this filter.

回答8:

writing this two line is more than enough for your work.

yourEditText.setKeyListener(null); 
yourEditText.setEnabled(false);

回答9:

set in XML

android:inputType="none" 

回答10:

Try using

editText.setEnabled(false);
editText.setClickable(false);

回答11:

android:editable

If set, specifies that this TextView has an input method. It will be a textual one unless it has otherwise been specified. For TextView, this is false by default. For EditText, it is true by default.

Must be a boolean value, either true or false.

This may also be a reference to a resource (in the form @[package:]type:name) or theme attribute (in the form ?[package:][type:]name) containing a value of this type.

This corresponds to the global attribute resource symbol editable.

android:editable="false" has been depreciated. Therefore you cant use it to make the edit text readonly.

I have done this using the bellow solution. Here I have used

android:inputType="none"

android:textIsSelectable="true"

android:focusable="false"

Give it try :)

<EditText
         android:id="@+id/et_newsgpa_university"
         android:layout_height="wrap_content"
         android:layout_width="match_parent"
         android:hint="@string/hint_educational_institute"
         android:textSize="@dimen/regular_text"
         android:inputType="none"
         android:textIsSelectable="true"
         android:focusable="false"
         android:maxLines="1"
         android:imeOptions="actionNext"/>

Try overriding the onLongClick listener of the edit text to remove context menu:

EditText myTextField = (EditText)findViewById(R.id.my_edit_text_id);
myTextField.setOnLongClickListener(new OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        return true;
    }
});

this is my implementation (a little long, but useful to me!): With this code you can make EditView Read-only or Normal. even in read-only state, the text can be copied by user. you can change the backgroud to make it look different from a normal EditText.

public static TextWatcher setReadOnly(final EditText edt, final boolean readOnlyState, TextWatcher remove) {
    edt.setCursorVisible(!readOnlyState);
    TextWatcher tw = null;
    final String text = edt.getText().toString();
    if (readOnlyState) {
            tw = new TextWatcher();

            @Override
            public void afterTextChanged(Editable s) {

            }
            @Override
            //saving the text before change
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            }

            @Override
            // and replace it with content if it is about to change
            public void onTextChanged(CharSequence s, int start,int before, int count) {
                edt.removeTextChangedListener(this);
                edt.setText(text);
                edt.addTextChangedListener(this);
            }
        };
        edt.addTextChangedListener(tw);
        return tw;
    } else {
        edt.removeTextChangedListener(remove);
        return remove;
    }
}

the benefit of this code is that, the EditText is displayed as normal EditText but the content is not changeable. The return value should be kept as a variable to one be able revert back from read-only state to normal.

to make an EditText read-only, just put it as:

TextWatcher tw = setReadOnly(editText, true, null);

and to make it normal use tw from previous statement:

setReadOnly(editText, false, tw);

This worked for me, taking several of the suggestions above into account. Makes the TextEdit focusable, but if user clicks or focuses, we show a list of selections in a PopupWindow. (We are replacing the wacky Spinner widget). TextEdit xml is very generic...

public void onCreate(Bundle savedInstanceState) {
    ....  
    fEditState = (EditText) findViewById(R.id.state_edit);

    fEditState.setLongClickable(false);
    fEditState.setKeyListener(null);
    fEditState.setFocusable(true);

    fEditState.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        public void onFocusChange(View v, boolean hasFocus)
        {
            if (hasFocus)
            {
               showStatesPopup();

            }
        }
    });

    fEditState.setOnClickListener(new Button.OnClickListener(){

        public void onClick(View arg0)
        {
           showStatesPopup();
        }
    });
    ....
}

private void showStatesPopup()
{
    // fPopupWindowStates instantiated in OnCreate()

    if (!fPopupWindowStates.isShowing()) {
        // show the list view as dropdown
        fPopupWindowStates.showAsDropDown(fEditState, -5, 0);
    }
}

If you just want to be able to copy text from the control but not be able to edit it you might want to use a TextView instead and set text is selectable.

code:

myTextView.setTextIsSelectable(true);
myTextView.setFocusable(true);
myTextView.setFocusableInTouchMode(true);
// myTextView.setSelectAllOnFocus(true);

xml:

<TextView
    android:textIsSelectable="true"
    android:focusable="true"
    android:focusableInTouchMode="true"     
    ...
/>
<!--android:selectAllOnFocus="true"-->

The documentation of setTextIsSelectable says:

When you call this method to set the value of textIsSelectable, it sets the flags focusable, focusableInTouchMode, clickable, and longClickable to the same value...

However I had to explicitly set focusable and focusableInTouchMode to true to make it work with touch input.

I had no problem making EditTextPreference read-only, by using:

editTextPref.setSelectable(false);

This works well when coupled with using the 'summary' field to display read-only fields (useful for displaying account info, for example). Updating the summary fields dynamically snatched from http://gmariotti.blogspot.com/2013/01/preferenceactivity-preferencefragment.html

private static final List<String> keyList;

static {
    keyList = new ArrayList<String>();
    keyList.add("field1");
    keyList.add("field2");
    keyList.add("field3");
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.preferences);

    for(int i=0;i<getPreferenceScreen().getPreferenceCount();i++){
        initSummary(getPreferenceScreen().getPreference(i));
    }
}

private void initSummary(Preference p) {
    if (p instanceof PreferenceCategory) {
        PreferenceCategory pCat = (PreferenceCategory) p;
        for (int i = 0; i < pCat.getPreferenceCount(); i++) {
            initSummary(pCat.getPreference(i));
        }
    } else {
        updatePrefSummary(p);
    }
}

private void updatePrefSummary(Preference p) {
    if (p instanceof ListPreference) {
        ListPreference listPref = (ListPreference) p;
        p.setSummary(listPref.getEntry());
    }
    if (p instanceof EditTextPreference) {
        EditTextPreference editTextPref = (EditTextPreference) p;
        //editTextPref.setEnabled(false); // this can be used to 'gray out' as well
        editTextPref.setSelectable(false);
        if (keyList.contains(p.getKey())) {
            p.setSummary(editTextPref.getText());
        }
    }
}

Set this in EdiTextView xml file

android:focusable="false"

回答19:

Use this code:

    editText.setEnabled(false);
    editText.setTextColor(ContextCompat.getColor(context, R.color.black);

Disabling editText gives a read-only look and behavior but also changes the text color to gray so setting its text color is needed.
