android在listview中用TBD替换空值

Question

SimpleCursorAdapter adapter = new SimpleCursorAdapter (this, R.layout.mytaskslayout, cursor, new String[] {"Aircraft","Discrepancy", "ARR_FLT", "ARR_Gate", "DPT_FLT", "DPT_Gate"}, new int[] {R.id.ac, R.id.discrepancy, R.id.arrac, R.id.arrgate, R.id.dptac, R.id.dptgate});

这里的一些值是空的。我不想显示空，而是显示待定。我能在这里做点什么吗。(我无法更改SQL)

Answer 1

迭代数组(填充listview)，数组中任何等于null的值都等于TBD

但从我看到的情况来看，您是在动态创建阵列，而不是从数据库

new String[] {"Aircraft","Discrepancy", "ARR_FLT", "ARR_Gate", "DPT_FLT", "DPT_Gate"}, new int[] {R.id.ac, R.id.discrepancy, R.id.arrac, R.id.arrgate, R.id.dptac, R.id.dptgate}
