Android:使多行edittext可滚动，在垂直滚动视图中禁用 [英] Android: Make multiline edittext scrollable, disable in vertical scroll view

问题描述

我正在开发一个可以在其中构建结构的应用程序.

I am developing an application in which i am struct at a point.

根据我的应用程序要求，我在xml中创建了水平滚动视图，然后在.java中创建了垂直滚动视图:

As according to my application requirement i created horizontal scrollview in xml and then vertical scrollview in .java as :

// Vertical Scroll view in Linear layout
ScrollView scrollView = new ScrollView(this);
scrollView.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));

然后我以编程方式创建了一个表格视图，并将其添加到scrollview中.我创建了多行编辑文本并将其禁用，因为我想在运行时设置文本并将其添加到表视图中作为一行..

Then i created a table view programatically and added it in scrollview. I created multiline edit text and disable it because i want to set text in it run time and added this in table view as a row..

EditText editText = new EditText(this);
editText.setId(1);
editText.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,0f));
editText.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);
editText.setGravity(Gravity.TOP|Gravity.LEFT);
editText.setHint("Comment");
editText.setSingleLine(false);
editText.setLines(5);
editText.setMaxLines(5);
editText.setText(CommentFromDB);
editText.setEnabled(false);

tableLayout.addView(editText);

// Add table in Horizontal scroll view
scrollView.addView(tableLayout);

现在我想使编辑文本可滚动，这是我通过代码实现的:

Now i want to make edit text scrollable which i achieve by code:

editText.setOnTouchListener(new OnTouchListener() {
        public boolean onTouch(View view, MotionEvent event) {
            if (view.getId() == 1) {
                view.getParent().requestDisallowInterceptTouchEvent(true);
                switch (event.getAction()&MotionEvent.ACTION_MASK){
                case MotionEvent.ACTION_UP:
                    view.getParent().requestDisallowInterceptTouchEvent(false);
                    break;
                case MotionEvent.ACTION_DOWN:
                    view.getParent().requestDisallowInterceptTouchEvent(false);
                    break;
                }
            }
            return false;
        }
    });

但是edittext并不容易滚动.我需要平滑滚动.

But the edittext is not scrolling easily. I need the smooth scrolling.

该怎么做，请指导我.

推荐答案

您可以做一件事.

只需将编辑文本的焦点设置为false.并应用到触摸监听器上.

Just make edit text focusable false. And apply on touch listener.

因此用户无法编辑文本，它将滚动为:

So user is not able to edit text and it will scroll as:

EditText editText = new EditText(this);
editText.setId(1);
editText.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,0f));
editText.setInputType(InputType.TYPE_TEXT_FLAG_MULTI_LINE);
editText.setGravity(Gravity.TOP|Gravity.LEFT);
editText.setHint("Comment");
editText.setSingleLine(false);
editText.setLines(5);
editText.setMaxLines(5);
editText.setText(CommentFromDB);
editTextRemark.setFocusable(false);

将onTouchListner应用为:

Apply onTouchListner as:

editTextRemark.setOnTouchListener(touchListener);

和

OnTouchListener touchListener = new View.OnTouchListener(){
    public boolean onTouch(final View v, final MotionEvent motionEvent){
        if(v.getId() == 1){
            v.getParent().requestDisallowInterceptTouchEvent(true);
            switch (motionEvent.getAction() & MotionEvent.ACTION_MASK){
                case MotionEvent.ACTION_UP:
                    v.getParent().requestDisallowInterceptTouchEvent(false);
                break;
            }
        }
        return false;
    }
};
