Alternating edit text hint not visible for Arabic language

问题

This is kind of weird that in my page where I have 6 edit text fields, only the alternative edit texts are showing hint and rest of them are not. This happens only from Android 4.0 and onward. I don't find any reasons for this. Any suggestions would be helpful.

Here is the code:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);    // Removes title bar
        setContentView(R.layout.register);

mLang = mPreference.getString("lang", "");

bBlood = (EditText) findViewById(R.id.editText8);
        bDOB = (EditText) findViewById(R.id.editText5);
        bAdd = (EditText) findViewById(R.id.editText6);
        bPhone = (EditText) findViewById(R.id.editText7);
        mProfile = (TextView) findViewById(R.id.textView1);


if(mLang.equalsIgnoreCase("English")){  
        }
        else{
            mProfile.setText(R.string.sign_up_arabic);
            bName.setHint(R.string.name_arabic);
            bDOB.setHint(R.string.name_arabic);
            bAdd.setHint(R.string.address_arabic);
            bPhone.setHint(R.string.name_arabic);
            bBlood.setHint(R.string.blood_arabic);
            mSignUp.setText(R.string.sign_arabic);
        }

And this is the layout for the above code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

    </ScrollView>

</RelativeLayout>

The Screenshot looks something like this:

回答1:

I have seen that this two EditText which have not shown hint are inputType set as "number" and "numberDecimal"., so please check one time removing input type.,It's may be creating issue.

回答2:

remove

 android:layout_below="@+id/textView1" 

from linear layout
