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

一个简单的解决方法是只编辑Text.setEnabled(false);editText.setEnabled(true);在Button onClick()方法中。

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);
}

下面的代码将帮助您创建可以从任何地方调用的通用函数。

import android.app.Activity
import android.content.Context
import android.support.design.widget.Snackbar
import android.view.View
import android.view.inputmethod.InputMethodManager

public class KeyboardHider {
    companion object {

        fun hideKeyboard(view: View, context: Context) {
            val inputMethodManager = context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
            inputMethodManager.hideSoftInputFromWindow(view.windowToken, 0)
        }

    }

}

使用一行代码从任何地方调用Above方法。

CustomSnackbar.hideKeyboard(view, this@ActivityName)

视图可以是任何内容,例如活动的根布局。

通过创建一个扩展来隐藏Kotlin中的软键盘,您可以全局使用该扩展。为此,需要创建一个Singleton类。

object Extensions {
    
      fun View.hideKeyboard() {
            val inputMethodManager =                                                 
            context.getSystemService(AppCompatActivity.INPUT_METHOD_SERVICE)           
            as InputMethodManager
            inputMethodManager.hideSoftInputFromWindow(windowToken, 0)
        }
    }

在需要隐藏键盘的片段类的活动中,可以使用mainlayout id调用此函数,如下所示

//constraintEditLayout is my main view layout, if you are using other layout like relative or linear layouts you can call with that layout id
constraintEditLayout.hideKeyboard()

在Kotlin试试这个

 private fun hideKeyboard(){
    val imm = activity!!.getSystemService(INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(activity!!.currentFocus!!.windowToken, 0)
}

在Java中尝试

 private void hideKeyboard(){
  InputMethodManager imm =(InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
  imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
}
final RelativeLayout llLogin = (RelativeLayout) findViewById(R.id.rl_main);
        llLogin.setOnTouchListener(
                new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View view, MotionEvent ev) {
                        InputMethodManager imm = (InputMethodManager) this.getSystemService(
                                Context.INPUT_METHOD_SERVICE);
                        imm.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
                        return false;
                    }
                });
