Ⅰ android 如何动态布局自定义view,不用XML.
可以直接new View来得到View对象来实现代码布局。以下为示例代码：
1.绝对布局
AbsoluteLayout abslayout=new AbsoluteLayout (this);
setContentView(abslayout);
Button btn1 = new Button(this);
btn1.setText(”this is a button”);
btn1.setId(1);
AbsoluteLayout.LayoutParams lp1 =
new AbsoluteLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT,
0,100);
abslayout.addView(btn1, lp1);
2.相对布局
RelativeLayout relativeLayout = new RelativeLayout(this);
setContentView(relativeLayout);
AbsoluteLayout abslayout=new AbsoluteLayout (this);
RelativeLayout.LayoutParams lp1 = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
lp1.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp1.addRule(RelativeLayout.CENTER_HORIZONTAL, RelativeLayout.TRUE);
relativeLayout.addView(abslayout ,lp1);
3.线性布局
LinearLayout ll = new LinearLayout(this);
EditText et = new EditText();
ll.addView(et);
//动态添加布局的方法1. LinearLayout ll = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main1,null); setContentView(ll); LinearLayout ll2 = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main2,ll); //这样 main2 作为 main1的子布局 加到了 main1的 根节点下
//动态添加布局的方法2 addView. LinearLayout ll = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main1,null); setContentView(ll); LinearLayout ll2 = (LinearLayout)this.getLayoutInflater().inflate(R.layout.main2,null); ll.addView(ll2);
Ⅱ android 怎么把俩个xml文件整合到一起
private ViewGroup group;
private ViewGroup main;
main = (ViewGroup) inflater.inflate(R.layout.main, null);//这里的R。latout.main就是当前布局
group = (ViewGroup) main.findViewById(R.id.viewGroup);
group.addView(imageViews[i]);//这样就把一个imageview（你可添加一个任意复杂的View,这个View实例化的时候指向你所谓的其他布局文件）加入当前布局中的某个ViewGroup里了，你布局时可定义一个LinearLayout id 设为(R.id.viewGroup）,oratation设为垂直，放到下面就是了。
