我想我尝试了这里提供的所有内容。我的活动中有ImageButton,我无法将其设置为切换到另一个活动(Log.d显示它甚至没有被点击)。
这是我的对话:
public class StarsActivity extends DialogFragment implements OnClickListener {
Dialog dialog;
Activity mActivity;
ImageButton nextQuestion;
final String LOG_TAG = "myLogs";
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_stars, null);
setCancelable(true);
return view;
}
/** The system calls this only when creating the layout in a dialog. */
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// The only reason you might override this method when using onCreateView() is
// to modify any dialog characteristics. For example, the dialog includes a
// title by default, but your custom layout might not need it. So here you can
// remove the dialog title, but you must call the superclass to get the Dialog.
dialog = super.onCreateDialog(savedInstanceState);
//Setting transparency for dialog background
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
//No title for dialog
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.activity_stars);
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
nextQuestion = (ImageButton)dialog.findViewById(R.id.nextQuestion);
Log.d(LOG_TAG, nextQuestion.toString());
nextQuestion.setOnClickListener(this);
mActivity = getActivity();
return dialog;
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.nextQuestion:
Log.d(LOG_TAG, "Dialog 2: ");
mActivity = getActivity();
Intent i = new Intent(mActivity, FinalActivity.class);
mActivity.startActivity(i);
this.dismiss();
break;
default:
break;
}
}
}
这是我的ImageButton xml:
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/nextQuestion"
android:background="@null"
android:src="@drawable/ic_content_nextbutton_02"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp" />
我希望有办法解决它。

我认为没有必要在StarsActivity中有一个Dialog实例,它已经从Dialog片段扩展。 以下代码执行您想要的所有内容
public class StarsActivity extends DialogFragment implements View.OnClickListener {
Activity mActivity;
ImageButton nextQuestion;
final String LOG_TAG = "myLogs";
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_stars, null);
nextQuestion = (ImageButton)view.findViewById(R.id.nextQuestion);
Log.d(LOG_TAG, nextQuestion.toString());
nextQuestion.setOnClickListener(this);
setCancelable(true);
return view;
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.nextQuestion:
Log.d(LOG_TAG, "Dialog 2: ");
mActivity = getActivity();
Intent i = new Intent(mActivity, FinalActivity.class);
mActivity.startActivity(i);
this.dismiss();
break;
default:
break;
}
}
}
请考虑将StarsActivity重命名为StarsDialog或其他内容。
