我的应用程序需要有多个ListView,当单击一个选项时,将打开第二个显示可缩放图片的活动。我的代码中的所有内容都会编译,打开正确的图片并进行相应的缩放。但是,我列表中的“名称”没有正确显示,所有人都说同样的事情:“com.example.poweruser.fcemsandroid.obstetric”。任何人都有解决方案来纠正这个?我的代码如下:
final Context context = getApplicationContext();
//list contains image name, image location
final List<imagedisplay> myImageList = new ArrayList<imagedisplay>();
myImageList.add(new imagedisplay("Aspirin", R.drawable.aspirin));
myImageList.add(new imagedisplay("Drug2", R.drawable.ekghomepic));
myImageList.add(new imagedisplay("Drug3", R.drawable.aspirin));
myImageList.add(new imagedisplay("Drug4", R.drawable.ekghomepic));
//define ListView and create onItemClick Listener
listview = (ListView) findViewById(R.id.obstetriclistview);
ArrayAdapter<imagedisplay> arrayAdapters = new ArrayAdapter<imagedisplay>(this, R.layout.support_simple_spinner_dropdown_item, myImageList);
listview.setAdapter(arrayAdapters);
listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent myIntent = new Intent(context, imagedisplay.class);
myIntent.putExtra("name", myImageList.get(position).getName());
myIntent.putExtra("imagePath", myImageList.get(position).getPath());
startActivityForResult(myIntent, 0);
}
});
}}
public class ImageDisplay {
private String Name;
private int Path; // use String if you use a path, in here i'm storing image in drawable
public ImageDisplay(){}
public ImageDisplay(String name, int path){
this.Name = name;
this.Path = path;
}
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public int getPath() {
return Path;
}
public void setPath(int path) {
this.Path = path;
}
}
第二个活动代码如下:
public class imagedisplay extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_imagedisplay);
ImageView imageView = (ImageView) findViewById(R.id.imageView3);
Intent myItent = getIntent();
String Name = myItent.getStringExtra("name"); //Do whatever you need with image title
int Path = myItent.getIntExtra("imagePath", 0); //pass this to ImageView
imageView.setImageResource(Path);
TouchImageView img = new TouchImageView(this);
img.setImageResource(Path);
img.setMaxZoom(4f);
setContentView(img);
}
}
