Question

点击我的列表项打开一个对话框。该对话框有2个图像视图和textview。问题是imageview未被点击。只有textview是可点击的。

以下是对话框的xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <ImageView
        android:id="@+id/pledge"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="10dp"
        android:clickable="true"
        android:contentDescription="@null"
        android:src="@drawable/uncheck" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/pledge"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="10dp"
        android:layout_toRightOf="@+id/pledge"
        android:gravity="center_vertical"
        android:text="@string/pledge" />

    <ImageView
        android:id="@+id/points"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/pledge"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="10dp"
        android:clickable="true"
        android:contentDescription="@null"
        android:src="@drawable/uncheck" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/pledge"
        android:layout_marginLeft="10dp"
        android:layout_marginTop="10dp"
        android:layout_toRightOf="@+id/points"
        android:gravity="center_vertical"
        android:text="@string/points" />

    <TextView
        android:id="@+id/confirm"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/points"
        android:layout_centerInParent="true"
        android:layout_marginBottom="5dp"
        android:layout_marginLeft="5dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/confirm"
        android:gravity="center"
        android:text="Confirm" />

</RelativeLayout>

只有@+id/confirm的TextView可以点击，但我想将上面定义的图片视图（@+id/pledge & @+id/points）也可以点击。

以下是课程

public class ConfirmDialogFragment extends DialogFragment {
    Boolean pointsChecked = false;
    Boolean pledgeChecked = false;
    ImageView pledge,points;

    @Override
    public void dismiss() {
        // TODO Auto-generated method stub
        super.dismiss();
    }

    public ConfirmDialogFragment() {

    }

    @Override
    public void onAttach(Activity activity) {
        // TODO Auto-generated method stub
        super.onAttach(activity);

    }

    @Override
    public void onDetach() {
        // TODO Auto-generated method stub
        super.onDetach();

    }


    @SuppressLint("InlinedApi")
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        Dialog dialog = super.onCreateDialog(savedInstanceState);
        dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
        getActivity();
        LayoutInflater inflater = (LayoutInflater) getActivity()
                 .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View v = inflater.inflate(R.layout.confirm_dialog_fragment,null);
                dialog.setContentView(v);

        final ImageView pledge = (ImageView) v
                .findViewById(R.id.pledge);
        pledge .setClickable(true);
        final ImageView points = (ImageView) v
                .findViewById(R.id.points);
        points.setClickable(true);
        TextView confirm = (TextView) v.findViewById(R.id.confirm);
        confirm.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                AppSession sInstance = AppSession.getInstance();
                sInstance.setConfirm(true);
                dismiss();
                Fragment fragment = new ListFragment();
                FragmentManager fragmentManager = getFragmentManager();
                FragmentTransaction ft = fragmentManager.beginTransaction();
                if (fragmentManager .getBackStackEntryCount() > 0){
                    fragmentManager .popBackStack();
                }
                ft.replace(R.id.frame_container, fragment).addToBackStack(null).commit();

            }
        });
        pledge.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub

                if (pledgeChecked) {
                    pledge.setBackgroundResource(R.drawable.uncheck);
                    pledgeChecked = false;

                } else {
                    pledge.setBackgroundResource(R.drawable.check);
                    pledgeChecked = true;
                }

            }
        });

        points.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                if (pointsChecked) {
                    points.setBackgroundResource(R.drawable.uncheck);
                    pointsChecked = false;

                } else {
                    points.setBackgroundResource(R.drawable.check);
                    pointsChecked = true;
                }
            }
        });



        return dialog;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

    }

}

我尝试过很多选项，在xml中使clickable = true并在代码中设置clickable，但似乎没有任何效果。我不确定我是否遗漏了一些东西，因为我过去曾做过类似的事情，但现在却在某种程度上挣扎了很长时间。请指教。

Answer 1

在XML文件中，您将图像设置为来源。然后，您通过更改背景以编程方式更改代码中的图像，但源仍将存在并完全隐藏背景。尝试使用

        points.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            if (pointsChecked) {
                points.setImageResource(R.drawable.uncheck);
                pointsChecked = false;

            } else {
                points.setImageResource(R.drawable.check);
                pointsChecked = true;
            }
        }
    });

编辑：通过自动生成的注释，我看到您正在使用Eclipse。我强烈建议您尝试使用Android Studio。我最近换了一个，我认为它更好。

Answer 2

points.setBackgroundResource(R.drawable.check)

对话框片段中的ImageView无法单击
