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
