VB制作软键盘

用API keybd_event来模拟按键过程，但是Ctrl+Alt+Del不能模拟，前面已经定义了各个按键的值，需要按什么键替换成对应的值就行了，由于是模拟键盘按键，所以按键发送的对象是当前激活的窗口。

android 如何让软键盘自动弹出？

可以通过下面的代码来实现Android自动弹出软键盘：

edittext.requestFocus(); //edittext是一个EditText控件

Timer timer = new Timer(); //设置定时器

timer.schedule(new TimerTask() {

@Override

public void run() { //弹出软键盘的代码

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);

imm.showSoftInput(edittext, InputMethodManager.RESULT_SHOWN);

imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,InputMethodManager.HIDE_IMPLICIT_ONLY);

}

}, 300); //设置300毫秒的时长

说明：同样是在写Techo Lite时遇到的问题。希望程序可以自动弹出软键盘，可是尝试了各种办法都没有效果。问题的原因似乎是必须等待UI绘制完成后弹出软键盘的代码才会有效。于是就采用了上面的方法。需要注意的是，在此之前必须让edittext获取焦点，不然也是无效的。

求c# 软键盘源代码

public partial class Form1 : Form { public Form1() { InitializeComponent(); this.InputLanguageChanged += new InputLanguageChangedEventHandler(Form1_InputLanguageChanged); }

void Form1_InputLanguageChanged(object sender, InputLanguageChangedEventArgs e) { //throw new Exception("The method or operation is not implemented."); for( int i=0;icomboBox1.Items.Count;i++) { if (InputLanguage.CurrentInputLanguage.LayoutName == comboBox1.Items[i].ToString()) { comboBox1.SelectedIndex = i; }

} }

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) { string strTemp = comboBox1.Items[comboBox1.SelectedIndex].ToString(); InputLanguageCollection collects = InputLanguage.InstalledInputLanguages; for (int i = 0; i collects.Count; i++) { if (collects[i].LayoutName == strTemp) InputLanguage.CurrentInputLanguage = collects[i]; } }

private void Form1_Load(object sender, EventArgs e) { InputLanguageCollection collects = InputLanguage.InstalledInputLanguages; for (int i = 0; i collects.Count; i++) { comboBox1.Items.Add(collects[i].LayoutName); } comboBox1.SelectedIndex = collects.IndexOf(InputLanguage.CurrentInputLanguage); }

private void button1_Click(object sender, EventArgs e) { this.textBox1.Focus(); IntPtr hwndInput = ImmGetContext(this.Handle); IntPtr dw1 = IntPtr.Zero; IntPtr dw2 = IntPtr.Zero; bool isSuccess = ImmGetConversionStatus(hwndInput, ref dw1, ref dw2); if (isSuccess) { int intTemp = dw1.ToInt32() IME_CMODE_SOFTKBD; if (intTemp 0) dw1 = (IntPtr)(dw1.ToInt32() ^ IME_CMODE_SOFTKBD); else dw1 = (IntPtr)(dw1.ToInt32() | IME_CMODE_SOFTKBD); } isSuccess = ImmSetConversionStatus(hwndInput, dw1, dw2); ImmReleaseContext(this.Handle, hwndInput); }

public const int IME_CMODE_SOFTKBD = 0x80;

[DllImport("imm32.dll", EntryPoint = "ImmGetContext")] public static extern IntPtr ImmGetContext( IntPtr hwnd ); [DllImport("imm32.dll", EntryPoint = "ImmGetConversionStatus")] public static extern bool ImmGetConversionStatus( IntPtr himc, ref IntPtr lpdw, ref IntPtr lpdw2 ); [DllImport("imm32.dll", EntryPoint = "ImmSetConversionStatus")] public static extern bool ImmSetConversionStatus( IntPtr himc, IntPtr dw1, IntPtr dw2 );

[DllImport("imm32.dll", EntryPoint = "ImmReleaseContext")] public static extern int ImmReleaseContext( IntPtr hwnd, IntPtr himc );

}}

Android如何让软键盘出现和消失

软键盘出现的代码如下:

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);

imm.toggleSoftInput(0, InputMethodManager.RESULT_SHOWN);

软键盘消失的代码如下：

InputMethodManager imm = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);

imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);

这两种功能的实现代码类似，在参数的部分修改一下就可以了。
