Question

I have an edittext in my app, which accepts only numbers. It is set to 0 by default. But when i enters some umbers, i want to overwrite the initial 0 in the left. Now i am having some problem with edittext. For example, when i inserts a 1, i want it to how 1, not 01. my code is like,

    value = (EditText)findViewById(R.id.value);
    value.addTextChangedListener(new TextWatcher() {
        public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) 
        {   
            if(arg0.length()==0)
            {
                value.setText("0");
                int i = value.getText().length();
                value.setSelection(i);
            }
        }

        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                int arg3) {
            // TODO Auto-generated method stub
            }

        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub
        }
    });

How can i achieve it? or is it possible?

You can set android:hint in your xml file.

For example,

<EditText
android:id="@+id/value"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="0"/>
