Question

    tv = new TextView[10];

    RelativeLayout rl = (RelativeLayout) findViewById(R.id.RL);
    RelativeLayout.LayoutParams lpFirst = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
    lpFirst.addRule(RelativeLayout.CENTER_HORIZONTAL);
    lpFirst.addRule(RelativeLayout.CENTER_VERTICAL);
    RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);

    for(int i = 0; i < 10; i++){
        tv[i] = new TextView(this);
        tv[i].setId(i + 1000);
        tv[i].setText("" + tv[i].getId());
    }
    rl.addView(tv[0], lpFirst);
    for(int i = 1; i < 10; i++){
        lp.addRule(RelativeLayout.RIGHT_OF, tv[i-1].getId());
        tv[i].setLayoutParams(lp);
        rl.addView(tv[i], lp);
    }

这是我的代码我想电视[1] ~TV [9]放在tv [0]的右侧但是它们放在左上方。我不知道是什么问题。

只需将LinearLayout放在XML

中的容器RelativeLayout中

head

并按ID获取该容器，并将每个子项添加到其中

我想动态创建视图并在屏幕中间显示它们
