Question

What is the error in radioButton1.getText().toString().equals("") in code below?

I want to force the user to fill in this field and if he leaves the field empty then toast a message that fills the required field. How do I do this?

page1.setOnClickListener(new View.OnClickListener() { 

public void onClick(View v) { 
    if(radioButton1.getText().toString().equals("")||radioButton2.getText().toString().equals("")||radioButton3.getText().toString().equals("")||radioButton4.getText().toString().equals("")
||petn.getText().toString().equals("")||breed.getText().toString().equals("")||color.getText().toString().equals("")||alergic.getText().toString().equals("")||ath_locat.getText().toString().equals("")||d_condi.getText().toString().equals("")||weight1.getText().toString().equals("")
    )
    { 
    Log.e("onclick", ",pd"); 
    Toast msg = Toast.makeText( 
    My2Activity.this,"Please fill the * required field",Toast.LENGTH_LONG); 
    msg.show(); 
     } 
    else{ 
    PostData(); 
    Intent d = new Intent(getApplicationContext(), 
    My1Activity.class); 
    startActivity(d); 
    } 
    } 
    });

Answer 1

if(radioButton1.isChecked())
{

}
else
{

}

you want to set OnCheckedChangeListener to radio button

radioButton1.setOnCheckedChangeListener(new RadioButton.OnCheckedChangeListener()
{
@Override
public void onCheckedChanged(CompoundButton arg0, boolean arg1) 
{

}
}
