Question

String[] textArray={"one","two","asdasasdf asdf dsdaa"};
int length=textArray.length;
RelativeLayout layout = new RelativeLayout(this);
RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(
        LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
for(int i=0;i<length;i++){
    TextView tv=new TextView(getApplicationContext());
    tv.setText(textArray[i]);
    relativeParams.addRule(RelativeLayout.BELOW, tv.getId());
    layout.addView(tv, relativeParams);
}

我需要做类似的事情......所以它会显示为

Answer 1

如果使用 RelativeLayout 并不重要，您可以使用 LinearLayout，然后这样做:

LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.VERTICAL);

这样做可以避免您尝试过的 addRule 方法。您可以简单地使用 addView() 添加新的 TextView。

完整代码:

String[] textArray = {"One", "Two", "Three", "Four"};
LinearLayout linearLayout = new LinearLayout(this);
setContentView(linearLayout);
linearLayout.setOrientation(LinearLayout.VERTICAL);        
for( int i = 0; i < textArray.length; i++ )
{
    TextView textView = new TextView(this);
    textView.setText(textArray[i]);
    linearLayout.addView(textView);
}
