Question

我想在我的Android应用程序中放置一个EditText，它将保持相同的三个布局或更具体的EditText字段将可用于具有不同其他属性的三个活动（如不同的TextView，Button等）任何人都可以告诉我怎么能我这样做？在此先感谢：）

public class PhoneEditText extends EditText {

    public PhoneEditText(Context context) {
        super(context);
        init();
    }

    public PhoneEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public PhoneEditText(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
            // set your input filter here
    }
}


n XML layout you would simply use the full path to your custom class instead EditText:

<my.package.path.to.PhoneEditText android:id="@+id/one"
   attribute="value (all EditText attributes will work as they did before)" />

<my.package.path.to.PhoneEditText android:id="@+id/two"
   attribute="value (all EditText attributes will work as they did before)" />


that's it....

如何在Android App中为多个xml布局提供EditText文本字段？
