我很喜欢使用动态布局来评论我的项目的一部分,但是当我将textview设置为动态,输出只出现在屏幕的顶部.并将输出放在其他输出上
RelativeLayout ll=(RelativeLayout) findViewById(R.id.rl);
for(int i = 0; i < 20; i++) {
TextView cb = new TextView(this);
cb.setText("YORUMLAR"+yorum[0]+i);
cb.setTextSize(30);
ll.addView(cb);
}
解决方法
您应该使用LinearLayout自动添加一个TextView.
假设您不能没有RelativeLayout生活,您将需要为您创建的所有TextView动态生成ids,以便将一个视图放在另一个视图下.这里是例子：
public class HelloWorld extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
RelativeLayout layout = (RelativeLayout)findViewById(R.id.layout);
Random rnd = new Random();
int prevTextViewId = 0;
for(int i = 0; i < 10; i++)
{
final TextView textView = new TextView(this);
textView.setText("Text "+i);
textView.setTextColor(rnd.nextInt() | 0xff000000);
int curTextViewId = prevTextViewId + 1;
textView.setId(curTextViewId);
final RelativeLayout.LayoutParams params =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.FILL_PARENT,RelativeLayout.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.BELOW,prevTextViewId);
textView.setLayoutParams(params);
prevTextViewId = curTextViewId;
layout.addView(textView,params);
}
}
}
