package com.example.jsapp;

import android.app.Activity;
import android.content.Context;

public class DynamicActivity extends Activity {

}

private void setView() {

llLayout.setOrientation(LinearLayout.HORIZONTAL);
btnClick.setOnClickListener(new OnClickListener() {
int count = 0;
@Override
public void onClick(View v) {
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//第一个参数为xml文件中view的id，第二个参数为此view的父组件，可以为null，android会自动寻找它是否拥有父组件
View view = inflater.inflate(R.layout.item, null);
TextView tvCaiLiao = (TextView) view.findViewById(R.id.tv_cai_liao);
TextView tvShuLiang = (TextView) view.findViewById(R.id.tv_shu_liang);

tvCaiLiao.setText("芹菜" + count);
tvShuLiang.setText("50g" + count);
llLayout.setOrientation(LinearLayout.VERTICAL);
llLayout.addView(view);
count++;
}
});
}
