2010.12.29(2)——— android 可伸缩的GridView

用 GridView 来实现九宫格布局并且一个格显示一个图片和一行字

1、ImageAdapter

package com.huitu.shyj.adapter;import android.content.Context;import android.view.Gravity;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.GridView;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.TextView;import com.huitu.shyj.activity.R;public class ImageAdapter extends BaseAdapter {private Context mContext;public ImageAdapter(Context c){mContext=c;}public int getCount() {return mThumbIds.length;}public Object getItem(int position) {return null;}public long getItemId(int position) {return 0;}public View getView(int position, View convertView, ViewGroup parent) {LinearLayout layoutView;if(convertView==null){layoutView=new LinearLayout(mContext);layoutView.setOrientation(LinearLayout.VERTICAL);ImageView iconView;TextView iconText;iconView=new ImageView(mContext);iconView.setLayoutParams(new GridView.LayoutParams(60,60));iconView.setScaleType(ImageView.ScaleType.CENTER_CROP);iconView.setImageResource(mThumbIds[position]);iconText=new TextView(mContext);iconText.setText(mThumbStrings[position]);LinearLayout.LayoutParams relParams=new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.FILL_PARENT);layoutView.addView(iconView, relParams);layoutView.addView(iconText, relParams);layoutView.setPadding(5, 10, 5, 10);layoutView.setGravity(Gravity.CENTER);}else {layoutView=(LinearLayout)convertView;}return layoutView;}private Integer[] mThumbIds={R.drawable.icon_1,R.drawable.icon_2,R.drawable.icon_3,R.drawable.icon_4,R.drawable.icon_5,R.drawable.icon_6,R.drawable.icon_7,R.drawable.icon_8,R.drawable.icon_9,R.drawable.icon_10,R.drawable.icon_11,R.drawable.icon_12,R.drawable.icon_13,R.drawable.icon_14,R.drawable.icon_15};private Integer[] mThumbStrings={R.string.app_act1,R.string.app_act2,R.string.app_act3,R.string.app_act4,R.string.app_act5,R.string.app_act6,R.string.app_act7,R.string.app_act8,R.string.app_act9,R.string.app_act10,R.string.app_act11,R.string.app_act12,R.string.app_act13,R.string.app_act14,R.string.app_act15};}

2、MainActivity

package com.huitu.shyj.activity;import java.io.File;import com.huitu.shyj.activity.R;import com.huitu.shyj.adapter.ImageAdapter;import com.huitu.shyj.util.SHYJTools;import android.app.Activity;import android.content.Intent;import android.content.SharedPreferences;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.GridView;import android.widget.AdapterView.OnItemClickListener;public class MainActivity extends Activity {public static final String ROOTPATH="/sdcard/SHYJ";public SharedPreferences settings;Intent intent;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                File file=new File(ROOTPATH);        if(!file.exists()){        file.mkdir();        }                //未设置跳转至设置页面        settings=getSharedPreferences(MXiTongSZ.SETTING_INFOS ,0);        String strwebservice=settings.getString(MXiTongSZ.WEBSERVICE, "");        String strlat=settings.getString(MXiTongSZ.LAT, "");        String strlon=settings.getString(MXiTongSZ.LON, "");        if(strwebservice.equals("")||strlat.equals("")||strlon.equals("")){        intent=new Intent();        intent.setClass(MainActivity.this, MXiTongSZ.class);        startActivity(intent);        }                SHYJTools.SHYJ_RECEIVE=settings.getInt(MXiTongSZ.RECEIVE, 0);                setTitle(R.string.app_name);        GridView gridView=(GridView)findViewById(R.id.main);        gridView.setAdapter(new ImageAdapter(this));                gridView.setOnItemClickListener(new OnItemClickListener(){public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {switch(arg2){case 0:intent=new Intent();intent.setClass(MainActivity.this, MYuJingXX.class);startActivity(intent);break;case 1:intent=new Intent();intent.setClass(MainActivity.this, MYingJiXY.class);startActivity(intent);break;case 2:intent=new Intent();intent.setClass(MainActivity.this, MYuJingCX.class);startActivity(intent);break;case 3:intent=new Intent();intent.setClass(MainActivity.this, MYuQingJS.class);startActivity(intent);break;case 4:intent=new Intent();intent.setClass(MainActivity.this, MShuiQingJS.class);startActivity(intent);break;case 5:intent=new Intent();intent.setClass(MainActivity.this, MZhiBanXX.class);startActivity(intent);break;case 6:intent=new Intent();intent.setClass(MainActivity.this, MYuAnCX.class);startActivity(intent);break;case 7:intent=new Intent();intent.putExtra("AppType", "EPCX");intent.setClass(MainActivity.this, MQueryEvent.class);startActivity(intent);break;case 8:intent=new Intent();intent.putExtra("AppType", "EVCX");intent.setClass(MainActivity.this, MQueryEvent.class);startActivity(intent);break;case 9:intent=new Intent();intent.setClass(MainActivity.this, MTianQiYB.class);startActivity(intent);break;case 10:intent=new Intent();intent.setClass(MainActivity.this, MPicActivity.class);intent.putExtra("AppType", "WXYT");startActivity(intent);break;case 11:intent=new Intent();intent.setClass(MainActivity.this, MPicActivity.class);intent.putExtra("AppType", "TFLJ");startActivity(intent);break;case 12:intent=new Intent();intent.setClass(MainActivity.this, MFangXunZZ.class);startActivity(intent);break;case 13:intent=new Intent();intent.setClass(MainActivity.this, MXiTongSZ.class);startActivity(intent);break;case 14:finish();break;default:finish();}}                });    }}

另一种方法不用自己写adapter
