Question

代码

 edtAddress = (EditText) findViewById(R.id.edtAddress);
 edtAddress.setTag(edtAddress.getKeyListener());
 edtAddress.setKeyListener(null);
 imgEdit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            edtAddress.setKeyListener((KeyListener) edtAddress.getTag());
        }
    });

嗨，我在打开应用程序时遇到问题，编辑文本无法编辑，但是当点击编辑按钮时，编辑文本就可以编辑了。

我已经完成了这个代码，但问题是，当我点击编辑按钮然后编辑文本（edtAddress）是可编辑的，但是，当键入任何字符时，编辑文本没有得到输入字符和应用程序崩溃。

那里有什么问题，建议我

Answer 1

尝试使用此代码，

edtAddress = (EditText) findViewById(R.id.edtAddress);
edtAddress.setEnabled(false);
imgEdit.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) 
    {
        edtAddress.setEnabled(true);
        edtAddress.requestFocus();
    }
});

Answer 2

您可以设置edittext disable。

edtOrganization.setFocusable(false);

现在您可以设置edittext enable。

edtFirst.setFocusable(true);
edtFirst.setFocusableInTouchMode(true);

Answer 3

您可以添加“requestFocus”，它会聚焦EditText

     <EditText...>
        <requestFocus />
     </EditText>

Answer 4

将其添加到EditText xml文件中：

<EditText ...
        android:clickable="false" 
        android:cursorVisible="false" 
        android:focusable="false" 
        android:focusableInTouchMode="false">
</EditText>

Answer 5

我添加了两个属性 android:singleLine="true" android:imeOptions="actionDone"

，一切开始正常运行。好吧，我仍然不了解原因，可能会对其进行深入研究，但希望这会有所帮助。

Edittext中的Edittext可编辑且不可编辑
