在LinearLayout中实现列表,列表采用LinearLayout横向布局-android学习

不多讲直接上代码

1.Activity 对应的布局文件如下:

<?xml version="1.0" encoding="utf-8"?><ScrollView xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:scrollbars="vertical"    android:fadingEdge="vertical">        <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical"         android:paddingTop="10dp"        android:id="@+id/funtable">            </LinearLayout>    </ScrollView>

2.Activity 实现类

package com.test.appdemo1.actlearn;import android.app.Activity;import android.app.AlertDialog.Builder;import android.content.DialogInterface;import android.os.Bundle;import android.util.Log;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.LinearLayout;import com.test.appdemo1.R;import com.test.appdemo1.R.string;/** * 功能学习  * @package com.test.appdemo1.actlearn * @author Administrator * @date 2014-3-1 下午11:16:31 */public class FunPageActivity extends Activity {    private LinearLayout funListView = null;        private Builder dialog = null;        protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.funtest);        funListView = (LinearLayout)findViewById(R.id.funtable);        dialog = new Builder(this);        initGridView();    }    /**     *初使化UI      */    private void initGridView() {        int ii = 1008601;int idx = 1;        LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT,1f);                        for(int i=1;i<=9;i++){            LinearLayout layout = new LinearLayout(this);            layout.setOrientation(LinearLayout.HORIZONTAL);            for(int j=1;j<=3;j++){                                            Button btn = new Button(this);                String key = "funPageBtn"+idx;idx++;                btn.setText(getString(getStringVal(key)));                Log.d("FUNCTION",key);                btn.setId(ii++);                btn.setOnClickListener(new BtnClick());                layout.addView(btn,param);            }            funListView.addView(layout);        }            }        /**     * 按纽单击处理     */    class BtnClick implements OnClickListener{        public void onClick(View v) {            Button btn = (Button)v;            //简单显示会话框            showDialog(""+btn.getText(),btn.getText().toString()+"=="+btn.getId());        }            }            /**     * 通过 R.string 类的属性名获取属性值     * @param str     * @return     */    public int getStringVal(String str){        try{            Class<string> cls = R.string.class;            return cls.getDeclaredField(str).getInt(null);        }catch(Exception ex){            ex.printStackTrace();        }        return 0;    }            /**     * 会话框     * @param title     * @param msg     */    private void showDialog(String title,String msg){        dialog.setIcon(R.drawable.ic_launcher).setPositiveButton("确定", new DialogInterface.OnClickListener() {            public void onClick(DialogInterface arg0, int arg1) {                arg0.cancel();            }        }).setTitle(title).setMessage(msg).show();    }    }

3.资源文件部分如下:

 <string name="funPageBtn1">底部选项卡</string>    <string name="funPageBtn2">Fun 2</string>    <string name="funPageBtn3">Fun 3</string>    <string name="funPageBtn4">Dialog Test</string>    <string name="funPageBtn5">Fun 2</string>    <string name="funPageBtn6">Fun 3</string>    <string name="funPageBtn7">Dialog Test</string>    <string name="funPageBtn8">Fun 2</string>    <string name="funPageBtn9">Fun 3</string>    <string name="funPageBtn10">Dialog Test</string>    <string name="funPageBtn11">Fun 2</string>    <string name="funPageBtn12">Fun 3</string>    <string name="funPageBtn13">Dialog Test</string>    <string name="funPageBtn14">Fun 2</string>    <string name="funPageBtn15">Fun 3</string>    <string name="funPageBtn16">Dialog Test</string>    <string name="funPageBtn17">Fun 2</string>    <string name="funPageBtn18">Fun 3</string>    <string name="funPageBtn19">Dialog Test</string>    <string name="funPageBtn20">Fun 2</string>    <string name="funPageBtn21">Fun 3</string>    <string name="funPageBtn22">Dialog Test</string>    <string name="funPageBtn23">Fun 2</string>    <string name="funPageBtn24">Fun 3</string>    <string name="funPageBtn25">Dialog Test</string>    <string name="funPageBtn26">Fun 2</string>    <string name="funPageBtn27">Fun 3</string>

4.效果
