问题描述

我需要单击EditText的drawableRight打开电话的通讯录. drawableRight上的单击事件运行正常，但是问题是，当我单击/触摸EditText上的任何位置时，它也执行单击事件并打开联系人列表.

I need to open phone's contact book on the click of EditText's drawableRight. Click event on drawableRight is working fine But the problem is, when I click/touch on anywhere on EditText it is also execute click event and open contact list.

我从这里drawableRight上的点击事件>请检查此链接.

I take help for manage click event on drawableRight from here Please check this link.

当我单击EditText时，我不想打开联系人列表，我只想单击drawableRight(图像)时打开它.那么如何解决这个问题呢?

I don't want to open contact list when I click on EditText, I only want to open it when I click drawableRight (image). So how solve this problem?

这是我的代码:

EditText mobile_number;
mobile_number = (EditText)view.findViewById(R.id.mobile_number1);
mobile_number.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                final int DRAWABLE_LEFT = 0;
                final int DRAWABLE_TOP = 1;
                final int DRAWABLE_RIGHT = 2;
                final int DRAWABLE_BOTTOM = 3;
                if(event.getAction()==MotionEvent.ACTION_UP){

                    if(event.getRawX()>=(mobile_number.getRight()-mobile_number.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width()));
                    {

                         Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
                        startActivityForResult(intent,PICK_CONTACT);

                        return true;
                    }
                }
                return true;
            }
        });

这是我的布局代码:

<LinearLayout
        android:layout_width="fill_parent"
        android:id="@+id/linearlayout_two1"
        android:layout_below="@+id/linearlayout_one1"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:layout_marginTop="20dp"
        android:orientation="vertical"
        >

        <EditText
            android:layout_width="300dp"
            android:hint="Enter Your Mobile Number"
            android:textSize="15sp"
            android:id="@+id/mobile_number1"
            android:paddingLeft="30dp"
            android:layout_height="wrap_content"
            android:drawableRight="@drawable/editbox_icon"
            />
</LinearLayout>

推荐答案

而不是使用getRawX()，请尝试将该行替换为

Instead of using getRawX(), try replacing that line with

if (event.getX() >= (mobile_number.getWidth() - mobile_number
        .getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {

我相信View.getRight()返回相对于其父视图的右边缘的位置，而TouchEvent.getRawX()返回屏幕上的绝对X位置.

I believe View.getRight() returns the position of the right edge of the View relative to its parent, while TouchEvent.getRawX() returns the absolute X position on the screen.

                // This detects the location of touch on ACTION_DOWN, but because it is
                // using getRawX() and getRight() and the EditText's parent is not at the
                // left of the screen, it will respond when clicked in the middle of the
                // EditText. Instead, use getX() and EditText.getWidth()
                if (event.getAction() == MotionEvent.ACTION_DOWN && event.getRawX() >= drawableLeft) {
                    touchX = event.getRawX();
