编码实现软件通知

构建新的xml

package cn.itcast.codeui;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        LinearLayout linearLayout = new LinearLayout(this);
        linearLayout.setOrientation(LinearLayout.VERTICAL);
        
        TextView textView = new TextView(this);
        textView.setText(R.string.hello);
        ViewGroup.LayoutParams textViewParams = new ViewGroup.LayoutParams(
        		ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        linearLayout.addView(textView, textViewParams);
        View partView = getPartUI();  //该部分是固定的 上面是动态的
        linearLayout.addView(partView);
        
        ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(
        		ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
        setContentView(linearLayout, layoutParams);
    }
    
    private View getPartUI(){
    	LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    	return inflater.inflate(R.layout.part, null); //由界面文件生成一个view对象，要不要挂一个父类元素
    }
}

part.xml
