Can you make an EditText input from right to left?

问题

I was wondering if you can control input on an EditText to move from right to left? The EditText would have to support insert/delete etc. from right to left as well. Is there a way to do this?

回答1:

It sounds like you just need to set gravity to the right.

回答2:

Add this to your editText

        android:textDirection="rtl"

回答3:

Just use this:

android:layout_gravity="start"
android:textAlignment="viewStart"

回答4:

try this code

//initialize
EditText userName = (EditText)findViewById(R.id.userName);

//set gravity for userName 
userName.setGravity(Gravity.RIGHT);

回答5:

The right way is to use:

android:textAlignment="viewStart"

As it will automatically work for LTR and RTL.

回答6:

There is the manual way to do it by using the following code :

@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {

    if (keyCode == KeyEvent.KEYCODE_MENU) {
        // Each time click Menu button on the bar
        // Set the cursor to the first index
        mEtEmail.setSelection(0); // YOUR EDIT TEXT
    } 

    return super.onKeyUp(keyCode, event);
}

p/s : Or you can change

KeyEvent.KEYCODE_MENU

follow your wishes,

Or you can try with Bidi.

Thanks,

you can add to your edittext in xml:

in case of left to right :

   android:textDirection="firstStrongLtr"                    

in case of right to left :

   android:textDirection="firstStrongRtl"

Try This....

1. Initialize User name and password fields.

   EditText username = (EditText) findViewById(R.id.username);
   
   EditText password = (EditText) findViewById(R.id.password);
   

2. Get current Locale for RTL languages like Arabic etc,.

   String getCurrentLocale = Locale.getDefault().getDisplayLanguage();
   

3. Then we should check which language is selected for RTL or LTR.

   if(getCurrentLocale.equalEgnoreCase("English")){          //LTR languages
   
         username.setGravity(Gravity.Left);
   
         password.setGravity(Gravity.Left);
   
    }else{                                                     //RTL languages
   
        username.setGravity(Gravity.Right);
   
        password.setGravity(Gravity.Right);
   
    }
   

4. Happy coding...!
