How To Check Whether A Value Is Entered In Editexts Before Submitting?

I have around 5 edittexts.When i click submit button,it has to check whether all fields are entered or not.Along with it if any value is not entered,the focus has to go to that des

Solution 1:

Android provides a setError() method for this:

if(edttxtDescription.getText().toString().trim().equals(""))
{
    edttxtDescription.setError("Please provide description");
}

Define a method to check whether your EditTexts have valid data:

privatebooleanvalidateEditTexts()
{
    boolean valid = true;

    if(edttxtDescription.getText().toString().trim().equals(""))
    {
        edttxtDescription.setError("Please provide description");
        valid = false;
    }

    // Similarly check all your EditTexts here and set the value of valid

    ......
    ......

    return valid;

}

To validate all your EditTexts, call validateEditTexts() which will return true or false accordingly.

btnsubmit.setOnClickListener(newOnClickListener() {

    @OverridepublicvoidonClick(View v) {

        if(validateEditTexts()){

            Send_reportclaim_Async reportsync=newSend_reportclaim_Async();
            reportsync.execute();

        }
    }
});

Try this. This will work.

Solution 2:

Check this:

for(EditText edit : editTextList){
    if(TextUtils.isEmpty(edit.getText()){
        // EditText is empty

    }
}

Solution 3:

Maintain array of EditText references: Like

EditText[] allEts = { caseno, dateloss, policy_rep, reg_book, Dri_lic };

Write the below code in onClick of submit button:

for (EditText editText : allEts) {
         Stringtext= editText.getText().toString();
         if (text.length() == 0) {
            editText.setError("enter this field");
            editText.requestFocus();
            break;
        }
    }

And, implement addTextChangedListener for all edittexts to clear the error after entering the text.

    caseno.addTextChangedListener(newTextWatcher() {

        @OverridepublicvoidonTextChanged(CharSequence s, int start, int before,
                int count) {
            Editabletext= caseno.getText();
            if (caseno.getError() != null && text != null
                    && text.length() > 0) {
                caseno.setError(null);
            }

        }

        @OverridepublicvoidbeforeTextChanged(CharSequence s, int start, int count,
                int after) {

        }

        @OverridepublicvoidafterTextChanged(Editable s) {

        }
    });

Solution 4:

Use this on your button click

if(!textView1.toString().isEmpty() && !textView2.toString().isEmpty() && ...)
{
 ............
}

Solution 5:

1) create this method

publicstaticbooleanisNullOrEmpty(String input) {
    return input == null || input.isEmpty();
}

2) send data to it for validation

booleananswer= isNullOrEmpty(editText.gettext().toString());
