How To Clear The Edittext When Onclick On Button
How do I clear the data which is given to an EditText dynamically when clicking the button? How do I write the code? What function or method do I use?
Solution 1:
Try
publicvoidclear(View v) {
edittext.setText("");
}
Where clear
is registered as onclick handler for the button in the layout file like this
<ImageButton android:id="@+id/ClearButton"
android:text="@string/ClearButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:onClick="clear" <<<--------here
android:src="@drawable/clear"
/>
Solution 2:
Button btn=(Button) findViewById(R.id.btn);
btn.setOnClickListener(newView.OnClickListener(){
publicvoidonClick(View v){
EditText et=(EditText) findViewById(R.id.et);
et.setText("");
}
});
Solution 3:
Its simple, I'm just considering that u know how to create the XML file... I'm putting across the java part of it....
publicclassStackOverFlowextendsActivity{
Button buttonToClick;
EditText editTextToclear;
@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
buttonToClick.setOnClickListener(newView.OnClickListener() {
publicvoidonClick(View v) {
editTextToclear.setText("");
}
});
}
}
Solution 4:
You can use function
myEditText.setText("");
Solution 5:
Register an OnClickListener for the button which deletes the text in the EditText. This document describes how to do that: http://developer.android.com/guide/topics/ui/ui-events.html
To clear the text in the listener just set an empty text: yourButton.setText("");
