我正在尝试检查我在 Eclipse 中编写的应用程序。由于某种原因，在模拟器上它无法加载。除了“不幸的是您的应用程序已停止”之外，它没有提供额外的信息。我无法通过 logcat 找出原因。如果我能得到任何帮助，我将不胜感激。
这是Java代码: 包 net.androidbootcamp.quickhealthysnackideasapp;
import android.support.v7.app.ActionBarActivity;
import android.content.Context;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;
public class MainActivity extends ActionBarActivity {
Integer[] Snacks = {R.drawable.snack1, R.drawable.snack2, R.drawable.snack3,
R.drawable.snack4,R.drawable.snack5};
ImageView pic;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView gr = (GridView)findViewById(R.id.gridView1);
final ImageView pic = (ImageView)findViewById(R.id.imgLarge);
gr.setAdapter(new ImageAdapter(this));
gr.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getBaseContext(), "Selected Snacks" + (arg2+1), Toast.LENGTH_SHORT).show();
pic.setImageResource(Snacks[arg2]);
}
});
}
public class ImageAdapter extends BaseAdapter{
private Context context;
public ImageAdapter(Context c)
{
// TODO Auto-generated constructor stub
context = c;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return Snacks.length;
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
@Override
public View getView(int arg0, View arg1, ViewGroup arg2) {
// TODO Auto-generated method stub
pic = new ImageView(context);
pic.setImageResource(Snacks[arg0]);
pic.setScaleType(ImageView.ScaleType.FIT_XY);
pic.setLayoutParams(new GridView.LayoutParams(188,200));
return pic;
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是xml代码:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="net.androidbootcamp.quickhealthysnackideasapp.MainActivity" >
<GridView
android:id="@+id/gridView1"
android:layout_width="wrap_content"
android:layout_height="250dp"
android:numColumns="3"
android:columnWidth="100dp"
android:horizontalSpacing= "5dp"
android:verticalSpacing= "5dp">
</GridView>
<Imageview
android:id="@+id/imgLarge"
android:layout_width="match_parent"
android:layout_height="match_parent"

大声笑 :)，将您的 XML 更改为
<ImageView
(大写V)
