java - 动态资源名称

Question

我想通过 for 循环填充多个 TextView。这不是实际的代码示例，但我希望它足以让您了解我正在尝试做什么。我什至不确定这是否可行，但我希望有人找到了方法。

    TextView dataTV0 = (TextView) v.findViewById(R.id.dataTV0);
    TextView dataTV1 = (TextView) v.findViewById(R.id.dataTV1);
    TextView dataTV2 = (TextView) v.findViewById(R.id.dataTV2);
    TextView dataTV3 = (TextView) v.findViewById(R.id.dataTV3);
    TextView dataTV4 = (TextView) v.findViewById(R.id.dataTV4);
    TextView dataTV5 = (TextView) v.findViewById(R.id.dataTV5);

    String[] data; //This is acquired from another source

 for (int i = 0; i < 6; i++){
            (String.format("dataTV%d", i).setText(data[i]);
        }

Answer 1

我认为一个选择是 Resources.getIdentifier()

for (int i = 0; i < 6; i++){
    TextView textView = (TextView) findViewById( getResources().getIdentifier(String.format("dataTV%d", i), "id", getPackageName() ) )
    if(textView != null)
        textView.setText(data[i]);
}

更新

为了避免过多的函数调用:

TextView textView;
Resources rresources = getResources();
String packageName = getPackageName();

for (int i = 0; i < 6; i++){
    textView = (TextView) findViewById( resources.getIdentifier(String.format("dataTV%d", i), "id", packageName ) )
    if(textView != null)
        textView.setText(data[i]);
}
