4 个解决方案

#1

Use this method in your Activity:

在你的活动中使用这个方法:

EditText et = (EditText) findViewById(R.id.text01);
et.setInputType(0x00002002);

or

或

EditText et = (EditText) findViewById(R.id.text01) ;
et.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

here text01 is id of EditText field in your R.java file;

这里text01是您的R中EditText字段的id。java文件;

Maybe a nicer solution would be using

也许有更好的解决办法

    et.setInputType(InputType.TYPE_CLASS_NUMBER 
                         | InputType.TYPE_NUMBER_FLAG_DECIMAL);

Edit: I have also added the flag InputType.TYPE_NUMBER_FLAG_DECIMAL to accept dobules too.

编辑:我还在puputtype中添加了旗帜。TYPE_NUMBER_FLAG_DECIMAL可以接受dobules。

#3

You can also use the setInputType(int type) function:

您还可以使用setInputType(int类型)函数:

EditText e
e.setInputType(InputType.Number) //Many other options are also available

#4

et.setRawInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

et.setRawInputType(InputType。TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL);

where setRawInputType it corresponds to the android:inputType attribute.

其中setRawInputType对应于android:inputType属性。
