So I want the text the person wrote in the EditText box to be printed on the screen when pressed enter or clicked on the button.
final TextView txt= findViewById(R.id.empty_text);
Button btn = findViewById(R.id.button_add);
final EditText tst = findViewById(R.id.test_textEdit);
final String value = tst.getText().toString();
btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
txt.append(value+"\n");
tst.setText("");
}
});
I think txt.append(value+"\\n"); I think I need something that tells the computer to print the text but I don't find one.
value
is only set once, and before you assign your ClickListener
. Just pull whatever text is present inside your EditText
every time onClick()
is called.
btn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
txt.setText(tst.getText().toString());
}
});
Edit: I just realised you were looking to update the TextView on an "Enter" key press as well. For that you can try:
tst.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int id, KeyEvent event) {
if (id == EditorInfo.IME_NULL) {
txt.setText(tst.getText().toString());
return true;
}
return false;
}
});
