How to automatically resize an EditText widget (with some attributes) in a TableLayout
- by steff
Hi everyone,
I have a layout issue. What I do is this:
create TableLayout in xml with zero children:
<TableLayout android:id="@+id/t_layout_contents"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@id/l_layout_tags"
android:stretchColumns="1"
android:paddingLeft="5dip"
android:paddingRight="5dip" />
Insert first row programmatically in onCreate():
tLayoutContents = (TableLayout)findViewById(R.id.t_layout_contents);
NoteElement nr_1 = new NoteElement(this);
tLayoutContents.addView(nr_1);
Class "NoteElement" extends TableRow. The 1st row just consists of a blank ImageView as a placeholder and an EditText to enter text. NoteElement's constructor looks like this:
public NoteElement(Context c) {
super(c);
this.context = c;
defaultText = c.getResources().getString(R.string.create_note_help_text);
imageView = new ImageView(context);
imageView.setImageResource(android.R.color.transparent);
LayoutParams params = new LayoutParams(0);
imageView.setLayoutParams(params);
addView(imageView);
addView(addTextField());
}
Method addTextField() specifies the attributes for the EditText widget:
private EditText addTextField() {
editText = new EditText(context);
editText.setImeOptions(EditorInfo.IME_ACTION_DONE);
editText.setMinLines(4);
editText.setRawInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);
editText.setHint(R.string.create_note_et_blank_text);
editText.setAutoLinkMask(Linkify.ALL);
editText.setPadding(5, 0, 0, 0);
editText.setGravity(Gravity.TOP);
editText.setVerticalScrollBarEnabled(true);
LayoutParams params = new LayoutParams(1);
editText.setLayoutParams(params);
return editText;
}
So far, so good. But my problem occurs as soon as the available space for the chars is depleted. The EditText does not resize itself but switches to a single line EditText.
I am desperatly looking for a way in which the EditText resizes itself in its height dynamically, being dependant on the inserted text length.
Does anyone have a hint on this?
Thanks & regards,
steff
