android – Set inputType for an EditText Programmatically?

Posted by: admin March 10, 2020 Leave a comment

Questions:

How do we set the input type for an EditText programatically? I’m trying:

mEdit.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);

it doesn’t seem to have any effect.

How to&Answers:

According to the TextView docs, the programmatic version of android:password is setTransformationMethod(), not setInputType(). So something like:

mEdit.setTransformationMethod(PasswordTransformationMethod.getInstance());

should do the trick.

Answer:

For setting the input type for an EditText programmatically, you have to specify that input class type is text.

editPass.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);

Answer:

i’ve solve all with

.setInputType(InputType.TYPE_CLASS_NUMBER);

for see clear data and

.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_VARIATION_PASSWORD);

for see the dots (if the data is a number, it isn’t choice che other class)

Answer:

Here are the various Input Types as shown on the standard keyboard.

Setting the input type programmatically

editText.setInputType(InputType.TYPE_CLASS_TEXT);

Other options besides TYPE_CLASS_TEXT can be found in the documentation.

Setting the input type in XML

<EditText
    android:inputType="text"
/>

Other options besides text can be found in the documentation.

Supplemental code

Here is the code for the image above.

public class MainActivity extends AppCompatActivity {

    EditText editText;
    TextView textView;
    List<InputTypeItem> inputTypes;
    int counter = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editText = findViewById(R.id.editText);
        textView = findViewById(R.id.textView);
        initArray();
    }

    public void onChangeInputTypeButtonClick(View view) {
        if (counter >= inputTypes.size()) {
            startOver();
            return;
        }
        textView.setText(inputTypes.get(counter).name);
        editText.setInputType(inputTypes.get(counter).value);
        editText.setSelection(editText.getText().length());
        counter++;
    }

    private void startOver() {
        counter = 0;
        textView.setText("");
        editText.setInputType(InputType.TYPE_CLASS_TEXT);
        InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(editText.getWindowToken(), 0);
    }


    private void initArray() {
        inputTypes = new ArrayList<>();
        inputTypes.add(new InputTypeItem("date",  InputType.TYPE_CLASS_DATETIME | InputType.TYPE_DATETIME_VARIATION_DATE));

        inputTypes.add(new InputTypeItem("textPhonetic",  InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PHONETIC));
        inputTypes.add(new InputTypeItem("textPostalAddress", InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_POSTAL_ADDRESS));
        inputTypes.add(new InputTypeItem("textShortMessage", InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_SHORT_MESSAGE));
        inputTypes.add(new InputTypeItem("textUri",  InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_URI));

Answer:

To only allow numbers:

password1.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_CLASS_NUMBER);

To transform (hide) the password:

password1.setTransformationMethod(PasswordTransformationMethod.getInstance());

Answer:

editText.setInputType(EditorInfo.TYPE_CLASS_NUMBER);

//you can change TYPE_… according to your requirement.

Answer:

This may be of help to others like me who wanted to toggle between password and free-text mode. I tried using the input methods suggested but it only worked in one direction. I could go from password to text but then I could not revert. For those trying to handle a toggle (eg a show Password check box) use

       @Override
        public void onClick(View v)
        {
            if(check.isChecked())
            {
                edit.setTransformationMethod(HideReturnsTransformationMethod.getInstance());
                Log.i(TAG, "Show password");
            }
            else
            {
                edit.setTransformationMethod(PasswordTransformationMethod.getInstance());
                Log.i(TAG, "Hide password");
            }
        }

I have to credit this for the solution. Wish I had found that a few hours ago!

Answer:

For Kotlin:

    val password = EditText(this)
    password.inputType = InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD
    password.hint = "Password"

Answer:

To unhide password:

editText.setInputType(
      InputType.TYPE_CLASS_TEXT|
      InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD
);

To hide password again:

editText.setTransformationMethod(PasswordTransformationMethod.getInstance());

Answer:

Try adding this to the EditText/TextView tag in your layout

android:password="true"

Edit: I just re-read your post, perhaps you need to do this after construction. I don’t see why your snippet wouldn’t work.

Answer:

I know the expected Answer is in Java . But here’s my 2 cents of advice always try to handle view related stuff in XML (atleast basic stuff) so I would suggest rather use a xml attribute rather than handling this use case in java

    <EditText
     android:inputType="textPassword"/>

Answer:

Hide:

edtPassword.setInputType(InputType.TYPE_CLASS_TEXT);
edtPassword.setTransformationMethod(null);

Show:

edtPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);                    
edtPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());

Answer:

password.setInputType(InputType.TYPE_CLASS_TEXT |
InputType.TYPE_TEXT_VARIATION_PASSWORD);

also you have to be careful that cursor moves to the starting point of the editText
after this function is called, so make sure that you move cursor to the end point again.

Answer:

field.setInputType(InputType.TYPE_CLASS_TEXT);
