How to set Min text (Mandatory) and Max text in EditText
You can try this code
First of all you set your maxlength in xml file like this
<EditText
android:id="@+id/editText"
android:layout_width="match_parent"
android:inputType="textPassword"
android:lines="1"
android:maxLength="15"
android:maxLines="1"
android:singleLine="true" />
Then in your code you can write like this
et_billamt.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
if (et_billamt.getText().toString().trim().length() < 5) {
et_billamt.setError("Failed");
} else {
// your code here
et_billamt.setError(null);
}
} else {
if (et_billamt.getText().toString().trim().length() < 5) {
et_billamt.setError("Failed");
} else {
// your code here
et_billamt.setError(null);
}
}
}
});
I designed if after no focus, so here you can write for min length condition and max length condition
Change your code TO this:
instead of value.getText().trim().length()
try using value.getText().length()<3
value.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
if (value.getText().toString().trim().length() < 3)
value.setError("Failed");
else
value.setError(null);
}
}
});
Try this
EditText value =(EditText) findviewbyId(R.id.urEditTextId);// this line must be oncreate
// place these line where u want to check
String ed1=value .getText().toString();
int size=ed1.length();
you can match the digit and perform appropriate action
if(size==0)
//Toast : kindly enter atleast one letter
if(size>175)
//Toast : max length 175 char
you can extend the EditText class, and override the onTextChanged method to monitor the text length change by yourself. Then you can control the limitation.
public class CustomEditText extends EditText{
public CustomEditText(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
@Override
protected void onTextChanged(CharSequence text, int start,
int lengthBefore, int lengthAfter) {
// TODO Auto-generated method stub
Log.i("length", "input text length = " + text.length());
super.onTextChanged(text, start, lengthBefore, lengthAfter);
}
}
