Question

我在ArrayAdapter中有这段代码：

public View getView(int position, View convertView, ViewGroup parent) {
    View row = super.getView(position, convertView, parent);

    Toast.makeText(getApplicationContext(), getItem(position).getString("text") + " = " + getItem(position).getString("my"), Toast.LENGTH_SHORT).show();

    if(getItem(position).getString("my") == "0") {
        row.setBackgroundColor(getResources().getColor(R.color.ekvi));
    }
    TextView tv = (TextView) row.findViewById(android.R.id.text1);
    tv.setText(getItem(position).getString("text"));
    tv.setTextColor(Color.BLACK);

    return row;
}

虽然未应用背景颜色。我检查了“我的”字符串，它实际上有时是“0”，所以它必须有效。

我做错了什么？

Answer 1

使用.equals() to compare Strings objects.

== compares Strings Refrences(memory location)
.equals() compares Strings characters(value)

<强>像

if(getItem(position).getString("my").equals("0")) {

ListView设置背景颜色
