我已经创建了一个注册页面，其中包括姓名、地址、PIN码、年龄等。我希望年龄和piicode字段应限制为数字。我曾尝试使用**android：inputType=“number”或android：inputType=“phone：“**但它不工作。请给予任何建议。

请尝试以下操作：

mPostalcode = (EditText) findViewById(R.id.epostalcode);
mPostalcode.setInputType(InputType.TYPE_NUMBER_FLAG_DECIMAL);

或尝试使用xml：

android:numeric="integer"

postalcodeEDT.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP){

            // Do what you want
            // (Check if 1.number, 2. Number within range
            return true;
        }
        return false;
    }
});

另外，将以下内容添加到邮政编码字段的xml文件中：

android:inputType="numberDecimal"

编辑：

对于在编辑框中检查年龄，您可能有一个onfocuschangelistener，如下所示：

ageEDT.setOnFocusChangeListener(new OnFocusChangeListener() {

public void onFocusChange(View v, boolean hasFocus) {
    if (!hasFocus) {
        EditText t = (EditText) v;
        if (t.getText() != null
                && !(t.getText().toString()).isEmpty()) {
            try {
                    // Allows age to be floating point too.
                Float i = Float.parseFloat(t.getText().toString());
                if (i >= 100 && i <=5) { 
                            // If age > 100 and <5. 
                    t.setText("");
                    t.setFocusable(true);
                    AlertUserforFocus(
                            "Age",
                            "Invalid Value. Please enter between 5 to 100 !!\n",
                            t);
                }
            } catch (NumberFormatException nfe) {
                // If characters other than numbers is entered
                t.setText("");
                AlertUserforFocus(
                        "Age",
                        "Invalid Value. Please enter between 5 to 100 !!\n",
                        t);
            }
        }
    }
}

});

备注：

AlertUserforFocus（String title，String message，final EditText t）是一个自定义的方法，用于向用户显示一个警告对话框。您可以根据自己的需要显示吐司或其他内容。
