我正在使用 json 方法在 listview 中获取文本和图像。我在列表视图中同时获取文本和图像。但我只在下一个活动中收到文本。我不知道如何在下一个活动中获取图像。任何人都可以帮助我...?
我的代码:
主要活动
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// getting values from selected ListItem
String title = ((TextView) view.findViewById(R.id.title)).getText().toString();
String desc = ((TextView) view.findViewById(R.id.desc)).getText().toString();
String image = ((ImageView) view.findViewById(R.id.image1)).getImageMatrix().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra("TAG_TITLE", title);
in.putExtra("TAG_DESC", desc);
in.putExtra("TAG_IMAGE", image);
startActivity(in);
}
});
}
SingleMenuItemActivity
公共类 SingleMenuItemActivity 扩展活动 {
Bitmap bmimage = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.setContentView(R.layout.single_list);
// getting intent data
Intent in = getIntent();
// Get JSON values from previous intent
String title = in.getStringExtra("TAG_TITLE");
String desc = in.getStringExtra("TAG_DESC");
String image = in.getStringExtra("TAG_IMAGE");
try {
URL url = new URL(image);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true);
conn.connect();
InputStream is = conn.getInputStream();
bmimage = BitmapFactory.decodeStream(is);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
TextView lbltitle = (TextView) findViewById(R.id.title);
TextView lbldesc = (TextView) findViewById(R.id.desc);
ImageView lblimage = (ImageView) findViewById(R.id.image1);
// Displaying all values on the screen
lbltitle.setText(title);
lbldesc.setText(desc);
lblimage.setImageBitmap(bmimage);
}
}
