安卓：添加两个文本视图编程 [英] Android: Add two text views programmatically

问题描述

我想添加视图编程的线性布局。

I am trying to add Views to a linear layout programmatically.

    LinearLayout layout     = (LinearLayout) findViewById(R.id.info);
    String [] informations  = topOffer.getInformations();
    TextView informationView;
    View line = new View(this);
    line.setLayoutParams(new LayoutParams(1, LayoutParams.FILL_PARENT));
    line.setBackgroundColor(R.color.solid_history_grey);
    for (int i = 0; i < informations.length; i++) {
        informationView = new TextView(this);
        informationView.setText(informations[i]);
        layout.addView(informationView, 0);
        layout.addView(line, 1);
    }

首先，我只是加入了informationsView，一切工作正常。还加入了线查看后对接，它具有以下错误崩溃：

First, I have only added the informationsView, and everything worked fine. Butt after adding also the line-View, it crashed with the following error:

java.lang.IllegalStateException：指定的孩子已经有一个父。你必须先调用removeView（）孩子的父母。

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

所以，我想addView（视图V，INT指数），但它具有相同的消息崩溃...

So I tried addView(View v, int index), but it crashed with the same message...

有人来过的解决方案？

谢谢， 马丁

推荐答案

由于gpmoo7说你需要创建每次在循环新视图

As gpmoo7 said you need to create every time a new view in the loop

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.linear);

    LinearLayout layout = (LinearLayout) findViewById(R.id.linear);

    String[] informations = new String[] { "one", "two", "three" };
    TextView informationView;

    for (int i = 0; i < informations.length; i++) {
        View line = new View(this);
        line.setLayoutParams(new LayoutParams(1, LayoutParams.MATCH_PARENT));
        line.setBackgroundColor(0xAA345556);
        informationView = new TextView(this);
        informationView.setText(informations[i]);
        layout.addView(informationView, 0);
        layout.addView(line, 1);
    }

}
