问题
就像主题所说的那样，我想仅在单击整行的相对复选框时才将列表视图行标记为选中。
有可能吗？
代码
主布局中的 ListView 视图：
<ListView
android:id="@+id/lv_anprreading_reading_list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/cb_anprreading_select_all"
android:listSelector="@drawable/list_selector_blue"
android:choiceMode="multipleChoice"
android:background="@drawable/grey_border_trasparent_bck" />
适配器布局：
<?xml version="1.0" encoding="utf-8"?>
<it.helian.infrastructure.FE.ui.widget.CheckableLinearLayout

android:layout_height="match_parent"
android:gravity="center_vertical"

android:padding="3dp" >
<it.helian.infrastructure.FE.ui.widget.InertCheckBox
android:id="@+id/itemCheckBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:focusable="false" />
<TextView

android:contentDescription="@string/dummy_string"
android:background="@color/transparent"
android:focusable="false" />
</it.helian.infrastructure.FE.ui.widget.CheckableLinearLayout>
惰性复选框：
import android.content.Context;
import android.util.AttributeSet;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.widget.CheckBox;
/**
* CheckBox that does not react to any user event in order to let the container handle them.
*/
public class InertCheckBox extends CheckBox {
// Provide the same constructors as the superclass
public InertCheckBox(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
// Provide the same constructors as the superclass
public InertCheckBox(Context context, AttributeSet attrs) {
super(context, attrs);
}
// Provide the same constructors as the superclass
public InertCheckBox(Context context) {
super(context);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
// Make the checkbox not respond to any user event
return false;
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Make the checkbox not respond to any user event
return false;
}
@Override
public boolean onKeyMultiple(int keyCode, int repeatCount, KeyEvent event) {
// Make the checkbox not respond to any user event
return false;
}
@Override
public boolean onKeyPreIme(int keyCode, KeyEvent event) {
// Make the checkbox not respond to any user event
return false;
}
@Override
public boolean onKeyShortcut(int keyCode, KeyEvent event) {
// Make the checkbox not respond to any user event
return false;
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
// Make the checkbox not respond to any user event
return false;
}
@Override
public boolean onTrackballEvent(MotionEvent event) {
// Make the checkbox not respond to any user event
return false;
}
}
可检查线性布局：
