Change

float inputFloaValue= Float.parseFloat(transfer_maney.getText().toString().trim());

to:

float inputFloatValue;
if (TextUtils.isEmpty(transfer_maney.getText().toString())) {
  inputFloatValue = 0F;
} else {
  inputFloatValue = Float.parseFloat(transfer_maney.getText().toString().trim());
}
