各位好: 我想要做一個Android應用，想讓執行畫面像 下圖 [IMG]http://i642.photobucket.com/albums/uu144/ aloha1003/2010-08-06_131638.png[/IMG]
http://i642.photobucket.com/albums/uu144/aloha1003/2010-08-06_131638.png 用GridView排列 我的原始碼是這樣 gc_mob.java [code]package gc.mob; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.GridView; import android.widget.AdapterView.*; import android.widget.Toast; import android.widget.*; public class gc_mob extends Activity { /** Called when the activity is first created. */ private GridView gv; private String[] items = { "RSS" , "Album" , "Blog" }; private int[] icons ={ R.drawable.sample_0, R.drawable.sample_1, R.drawable.sample_2 }; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); gv = (GridView) findViewById(R.id.gridview); GC_MainGridView gc_adapter = new GC_MainGridView(this,items,icons); gv.setAdapter(gc_adapter); gv.setOnItemClickListener(new OnItemClickListener(){ public void onItemClick(AdapterView<?> parent,View v,int position , long id){ Toast.makeText(gc_mob.this, "" + position, Toast.LENGTH_SHORT).show(); } }); } }[/code] main.xml [code]<GridView xmlns:android="http://schemas.android.com/apk/res/ android" android:id="@+id/gridview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:columnWidth="90dp" android:numColumns="auto_fit" android:verticalSpacing="10dp" android:horizontalSpacing="10dp" android:stretchMode="columnWidth" android:gravity="center" > <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/icon"></ ImageView> <TextView android:text="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/text"></ TextView> </GridView>[/code] GC_MainGridView.java [code]package gc.mob; import android.view.View; import android.view.ViewGroup; import android.widget.BaseAdapter; import android.widget.ImageView; import android.content.*; import android.widget.*; public class GC_MainGridView extends BaseAdapter { private Context _con; private String[] _items; private int[] _icons; public GC_MainGridView(Context con, String[] items, int[] icons) { _con = con; _items = items; _icons = icons; } @Override public int getCount() { // TODO Auto-generated method stub return _icons.length; } @Override public Object getItem(int position) { // TODO Auto-generated method stub return _icons[position]; } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View v, ViewGroup parent) { // TODO Auto-generated method stub ImageView imageView; if (v == null) { // if it's not recycled, initialize some attributes imageView = new ImageView(_con); ImageView iv = (ImageView) imageView.findViewById(R.id.icon); TextView tv = (TextView) imageView.findViewById(R.id.text); iv.setImageResource(_icons[position]); tv.setText(_items[position]); }else { imageView = (ImageView) v; } return imageView; } } [/code] 可是拿去給模擬器執行的時候 都會出現 gc_android(程序:gc.mob)異常終止，請再試一次的錯誤訊息 開Debug模式，它提供給我的訊息是 Thread [<1> main] (Suspended (exception RuntimeException)) ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2663 ActivityThread.handleLaunchActivity(ActivityThread$ActivityRecord, Intent) line: 2679 ActivityThread.access$2300(ActivityThread, ActivityThread $ActivityRecord, Intent) line: 125 ActivityThread$H.handleMessage(Message) line: 2033 ActivityThread$H(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 123 ActivityThread.main(String[]) line: 4627 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 521 ZygoteInit$MethodAndArgsCaller.run() line: 868 ZygoteInit.main(String[]) line: 626 NativeStart.main(String[]) line: not available [native method] Source not found. 請問我該怎麼解決 謝謝 -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
