如果是这样的话,那么ScrollView就相当无能了(难以置信),或者有其他的方法可以解决。以下是我的代码。在循环第二次执行时会出错(也就是注释掉的地方)。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ondemandandautomatic_dynamicauthorize);
ScrollView svh = (ScrollView) findViewById(R.id.scrollViewHost);
// Contacts data snippet adapted from
// http://saigeethamn.blogspot.com/2011/05/contacts-api-20-and-above-android.html
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur
.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
// Create a Linear Layout for each contact?
LinearLayout llay = new LinearLayout(this);
llay.setOrientation(LinearLayout.HORIZONTAL);
LinearLayout.LayoutParams llp = new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
llp.weight = 1.0f;
CheckBox cbOnDemand = new CheckBox(getApplicationContext());
cbOnDemand.setTag(id);
cbOnDemand.setLayoutParams(llp);
llay.addView(cbOnDemand);
CheckBox cbTime = new CheckBox(getApplicationContext());
cbOnDemand.setTag(id);
cbTime.setLayoutParams(llp);
llay.addView(cbTime);
CheckBox cbSpace = new CheckBox(getApplicationContext());
cbOnDemand.setTag(id);
cbSpace.setLayoutParams(llp);
llay.addView(cbSpace);
TextView tv = new TextView(getApplicationContext());
tv.setTag(id);
tv.setText(name);
tv.setLayoutParams(llp);
llay.addView(tv);
svh.addView(llay); // it transports me to Eclipse's Debug perspective when I hit this line the SECOND time around.
// One cat on stackOverflow said to do this, another said it
// would be unnecessary
svh.invalidate();
}
}
}
