Android development listview+edittext-deadly focus and soft keyboard problem resolution "original link"This article perfectly solves the bug that I haven't concluded for a few months ...Thank you for sharing the technology talent ~How did I get into this big hole ...Demand:A edittext in the ListView accepts the user input message.Pre-solutions:Bind the focus event to this edittext .... The tragedy began ...You know? When this edittextview is ordered,

addition, if a cell needs to occupy multiple locations, it can be set using Android:layout_rowspan and Android:layout_columnspan.The biggest problem with GridLayout is that the space occupied by the entire table is indeterminate, and the line spacing is determined by the height of the largest cell in the row, which is determined by the cell with the widest range of columns. In the above example, some of the controls are outside the screen. The size of each cell defaults to wrap_content, and if

When do I use a service when I use thread? Today I also say my understanding and summary.First, you need to understand several features of the service.(1) By default, the servi

Always remember to close the sensor when you don't need it, especially when the activity is tentative. Ignoring this will consume the battery in a few hours. Note that when the screen is off, the system will not automatically turn off the sensor. Three Common Sensors (1) Acceleration Sensor Three floating point models can be obtained through this

Turn writing code into a simple copy operation. One of the Code generators is --------- android, findViewById By writing a simple configuration file, the code is automatically extended to generate the corresponding code, which can be a little lazy. The configuration file is as follows: TextView:moneyTextView:nameTextView:ageImageView:headImg The ruby code generator is as follows: require 'erb'class Find

For example, tools:context this is to layout associate this file with the following Activity , so that when the editor shows the layout effect, it can target Activity some of the properties f

Sending text messages in Android is simple,The first thing to do is to add the required permissions in the Mainfest.xml:uses-permissionAndroid:name= "Android.permission.SEND_SMS">uses-permission>uses-permissionAndroid:name= "Android.permission.READ_SMS">uses-permission>uses-permissionAndroid:name= "Android.permission.RECEIVE_SMS">uses-permission>For later testing convenience, simply add all the SMS permissions.Method 1: Public class extends Activity {
