我的布局中有一个EditText和一个Button。
在编辑字段中写入并单击按钮后,我想在触摸键盘外部时隐藏虚拟键盘。我假设这是一段简单的代码,但我在哪里可以找到它的示例?

当前回答
在如此的搜索中,我找到了一个适合我的答案
// Show soft-keyboard:
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
// Hide soft-keyboard:
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
其他回答
简单易用的方法,只需调用hideKeyboardFrom(YourActivity.this);隐藏键盘
/**
* This method is used to hide keyboard
* @param activity
*/
public static void hideKeyboardFrom(Activity activity) {
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
}
感谢上帝,它在11年后得到了官方支持
首先将依赖实现“androidx.core:core-ktx:1.7.0”添加到appgradle
然后从ViewCompat或WindowCompat类获取InsetsController。
最后使用InsetsController的hide()和show()函数
已编辑添加对Dialog的支持。在BottomSheetDialog中提供@隆德夫。使用更安全的方式获取活动,而不是直接从上下文中强制转换。
import android.app.Activity
import android.app.Dialog
import android.content.Context
import android.content.ContextWrapper
import android.view.View
import androidx.core.view.ViewCompat
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.fragment.app.Fragment
fun View.showKeyboard() = ViewCompat.getWindowInsetsController(this)?.show(WindowInsetsCompat.Type.ime())
fun View.hideKeyboard() = ViewCompat.getWindowInsetsController(this)?.hide(WindowInsetsCompat.Type.ime())
fun Dialog.showKeyboard() = window?.decorView?.showKeyboard()
fun Dialog.hideKeyboard() = window?.decorView?.hideKeyboard()
fun Context.showKeyboard() = getActivity()?.showKeyboard()
fun Context.hideKeyboard() = getActivity()?.hideKeyboard()
fun Fragment.showKeyboard() = activity?.showKeyboard()
fun Fragment.hideKeyboard() = activity?.hideKeyboard()
fun Activity.showKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.show(WindowInsetsCompat.Type.ime())
fun Activity.hideKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.hide(WindowInsetsCompat.Type.ime())
fun Context.getActivity(): Activity? {
return when (this) {
is Activity -> this
is ContextWrapper -> this.baseContext.getActivity()
else -> null
}
}
下面是旧的anwser
下面是github上的简单项目
import android.app.Activity
import android.app.Dialog
import android.content.Context
import android.content.ContextWrapper
import android.view.View
import androidx.core.view.ViewCompat
import androidx.core.view.WindowCompat
import androidx.core.view.WindowInsetsCompat
import androidx.fragment.app.Fragment
fun View.showKeyboard() = ViewCompat.getWindowInsetsController(this)?.show(WindowInsetsCompat.Type.ime())
fun View.hideKeyboard() = ViewCompat.getWindowInsetsController(this)?.hide(WindowInsetsCompat.Type.ime())
fun Dialog.showKeyboard() = window?.decorView?.showKeyboard()
fun Dialog.hideKeyboard() = window?.decorView?.hideKeyboard()
fun Context.showKeyboard() = getActivity()?.showKeyboard()
fun Context.hideKeyboard() = getActivity()?.hideKeyboard()
fun Fragment.showKeyboard() = activity?.showKeyboard()
fun Fragment.hideKeyboard() = activity?.hideKeyboard()
fun Activity.showKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.show(WindowInsetsCompat.Type.ime())
fun Activity.hideKeyboard() = WindowCompat.getInsetsController(window, window.decorView)?.hide(WindowInsetsCompat.Type.ime())
fun Context.getActivity(): Activity? {
return when (this) {
is Activity -> this
is ContextWrapper -> this.baseContext.getActivity()
else -> null
}
}
如果这里的所有其他答案都不适合您,那么还有另一种手动控制键盘的方法。
创建一个用于管理EditText的某些财产的函数:
public void setEditTextFocus(boolean isFocused) {
searchEditText.setCursorVisible(isFocused);
searchEditText.setFocusable(isFocused);
searchEditText.setFocusableInTouchMode(isFocused);
if (isFocused) {
searchEditText.requestFocus();
}
}
然后,确保在EditText的焦点上打开/关闭键盘:
searchEditText.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if (v == searchEditText) {
if (hasFocus) {
// Open keyboard
((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).showSoftInput(searchEditText, InputMethodManager.SHOW_FORCED);
} else {
// Close keyboard
((InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(searchEditText.getWindowToken(), 0);
}
}
}
});
现在,每当您想要打开键盘时,请手动调用:
setEditTextFocus(true);
对于结束通话:
setEditTextFocus(false);
下面是隐藏和显示方法。
科特林
fun hideKeyboard(activity: Activity) {
val v = activity.currentFocus
val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
assert(v != null)
imm.hideSoftInputFromWindow(v!!.windowToken, InputMethodManager.HIDE_NOT_ALWAYS)
}
private fun showKeyboard(activity: Activity) {
val v = activity.currentFocus
val imm = activity.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
assert(v != null)
imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT)
}
Java
public static void hideKeyboard(Activity activity) {
View v = activity.getCurrentFocus();
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null && v != null;
imm.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
private static void showKeyboard(Activity activity) {
View v = activity.getCurrentFocus();
InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
assert imm != null && v != null;
imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
}
试试这个强制完全android软输入键盘
在Helper类中创建方法。
InputMethodManager imm = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null)
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
