Anda perlu melakukan dua hal:
- Menggunakan
mListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
- Buat tampilan baris kustom Anda diterapkan
Checkable.
Jadi saya pikir solusi yang lebih baik adalah menerapkan Checkable di dalam LinearLayout batin Anda: (terima kasih kepada daichan4649, dari tautannya, https://gist.github.com/daichan4649/5245378 , saya mengambil semua kode yang ditempel di bawah)
CheckableLayout.java
package daichan4649.test;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.Checkable;
import android.widget.LinearLayout;
public class CheckableLayout extends LinearLayout implements Checkable {
private static final int[] CHECKED_STATE_SET = { android.R.attr.state_checked };
public CheckableLayout(Context context) {
super(context, null);
}
public CheckableLayout(Context context, AttributeSet attrs) {
super(context, attrs, 0);
}
public CheckableLayout(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
private boolean checked;
@Override
public boolean isChecked() {
return checked;
}
@Override
public void setChecked(boolean checked) {
if (this.checked != checked) {
this.checked = checked;
refreshDrawableState();
for (int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
if (child instanceof Checkable) {
((Checkable) child).setChecked(checked);
}
}
}
}
@Override
public void toggle() {
setChecked(!checked);
}
@Override
protected int[] onCreateDrawableState(int extraSpace) {
final int[] drawableState = super.onCreateDrawableState(extraSpace + 1);
if (isChecked()) {
mergeDrawableStates(drawableState, CHECKED_STATE_SET);
}
return drawableState;
}
}
