问题描述
我不知道是否有一种方法可以动态地创建一个predefined衬垫布局中一个TextView额外的线性布局。这是我的code等你拿我是问什么的要点是:
I was wondering if there is a way to dynamically create an additional linear layout with a textview within a predefined liner layout. THis is my code so you get the gist of what I am asking:
LinearLayout MainLL= (LinearLayout) findViewById(R.id.myLayoutId);
for(int i=0; i<5; i++)
{
LinearLayout childLL= new LinearLayout(this);
childLL.setOrientation(LinearLayout.VERTICAL);
childLL.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
childLL.setGravity(Gravity.LEFT);
TextView text = new TextView(this);
text.setText("The Value of i is :"i);
text.setTextSize(12);
text.setGravity(Gravity.LEFT);
text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
childLL.addView(text);
MainLL.addView(childLL);
}
我的问题是,我只得到我的值是:0作为输出,即第一个实例。
My problem is that I am only getting "The Value of i is :0" as the output, i.e. the first instance.
任何帮助将是非常美联社preciated
Any help would be much appreciated
推荐答案
您不需要包装其他的LinearLayout内TextView的,你可以做:
You don't need to wrap the TextView inside another LinearLayout, you can do just:
LinearLayout MainLL= (LinearLayout) findViewById(R.id.myLayoutId);
for(int i=0; i<5; i++){
TextView text = new TextView(this);
text.setText("The Value of i is :"+i); // <-- does it really compile without the + sign?
text.setTextSize(12);
text.setGravity(Gravity.LEFT);
text.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
MainLL.addView(text);
}
