问题 I'm fairly new to Android development and am currently working on an app that allows people to type text into a box and the text is displayed on a Bitmap on screen. I have a text box in the activity that listens for changes. Each time you type text it calls functions to figure out how to best format the text on the image, then updates the image with the new text. It works fine for just a little bit of text, but when there's a lot, the calculations become slower and the device begins to freeze

一、文本框动态跟随显示输入以及控制字数 在编写代码的时候，如果需要让文本框能够跟随编辑框输入的内容而显示出来的话，可以使用TextWatcher。 另外，使用该接口可以控制编辑状态和效果，具体看代码。 完整代码： package com.xsjayz.textwatcher; import android.app.Activity; import android.graphics.Color; import android.os.Bundle; import android.text.Editable; import android.text.TextWatcher; import android.widget.EditText; import android.widget.TextView; import android.widget.Toast; /** * EditText在布局中经常用到，对EditText中输入的内容也经常需要进行限制， * 可以通过TextWatcher去观察输入框中输入的内容来限制输入字符个数。 * * @author XuShaoJie * @version 2012-08-30 */ public class TextWatcherActivity extends Activity { private TextView textView;

问题 I have a custom list adapter with one list item having three edit texts. And I Have a date picker for one of them. When a date is set, the corressponding model for the adapter is saved with the date correctly. But for the other edit texts, i just want the entered text to be stored in the list. And I use textwatcher to accomplish the task. My problem is the text watcher fires multiple times (5 times to be exact) for a single entry in the view. If one of the edit texts works correctly, why not

问题 In the login panel of my app, I divided the country calling code and the remaining numbers in two editable TextView as below: I want to use international formatting standard in the TextView on the right.

When I input a part of a product name, the table redraws with only those products that contain entered text in it. But I used

问题 new SO user here and I'm new to android as well. I need help doing a simple calculation between two edittext boxes - without a button, using a textwatcher, so that after the user is done using the edittext boxes it can add the two together and output the answer in a textview.
