我有listview。其中包含ImageButton，Button和TextView。如果我按下imagebutton，它将进入相机。我不知道如何在imagebutton中设置图像。我的代码在这里。任何人都帮助我。
public class AddCertificateActivity extends ActionBarActivity {
private String[] UnderGraduate={"Passport Front","Passport back","10th Mark Sheet",
"12th Mark Sheet","IELTS or English proficiency letter by School"};
private String[] Graduate={"Passport Front","Passport back","10th Mark Sheet",
"12th Mark Sheet","Ist year Detail marks","2nd year Detail marks",
"3rd year Detail marks","Final year Detail marks","Degree Copy",
"IELTS or English proficiency letter by School","Experience Certificate( if any)"};
private String[] PostGraduate={"Passport Front","Passport back","10th Mark Sheet",
"12th Mark Sheet","Ist year Detail marks","2nd year Detail marks",
"3rd year Detail marks","Final year Detail marks","Degree Copy",
"IELTS or English proficiency letter by School","Current Resume",
"Experience Certificate( if any)"};

此方法放入您的activityclass
修改
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE
&& resultCode == RESULT_OK) {
selectedImagePath = (mPhotoUri.getPath());
if (selectedImagePath == null) {
return;
}
photo = (Bitmap) BitmapFactory.decodeFile(selectedImagePath);
if(adapter!=null){
adapter.btn_Image.setImageBitmap(photo);
}
}
将此方法从mainactivity调用到适配器.. 像这样 ：
public class CertificateAdapter extends ArrayAdapter<String> {
AddCertificateActivity context;
String[] data;
int layoutResourceId;
private static final int MEDIA_TYPE_IMAGE = 1;
private Uri fileUri;
private static final int CAMERA_REQUEST_CODE=100;
public Bitmap bitmap;
public CertificateAdapter(AddCertificateActivity context,int resources, String[] data) {
super(context,resources,data);
this.context=context;
this.data=data;
this.layoutResourceId=resources;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater mInflater=((Activity)context).getLayoutInflater();
convertView = mInflater.inflate(R.layout.list_row, null);
btn_Image = (ImageButton)convertView.findViewById(R.id.img_Certificate);
text=(TextView)convertView.findViewById(R.id.header);
add=(Button)convertView.findViewById(R.id.btn_Add);
convertView.setTag(holder);
}
text.setText(data[position]);
btn_Image.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent cameraIntent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
context.startActivityForResult(cameraIntent, CAMERA_REQUEST_CODE);
}
});
return convertView;
}
编辑:::
CertificateAdapter adapter=new CertificateAdapter(this,R.layout.list_row,data);
listView.setAdapter(adapter);
