Many times, when we use the application, there will be an input method soft keyboard pop-up problem, usually, we will let the user click the Return button or the next step to hide the soft keyboard. For a better experience, we can implement when the user finishes using the soft keyboard. Click on an empty area to achieve hidden functionality. Effect:

Code implementation

code block syntax follows the standard markdown code, for example:

Of course we have a simpler way to implement this function, just rewrite the Ontouchevent method. The code is as follows:

?

// 点击空白区域 自动隐藏软键盘    public boolean onTouchEvent(MotionEvent event) {        if(null != this.getCurrentFocus()){            /**             * 点击空白位置 隐藏软键盘             */            InputMethodManager mInputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);            return mInputMethodManager.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);        }        return super .onTouchEvent(event);    }

Use a baseactivity to do some common operations, other activity is inherited from the base class activity, then all the interface can be realized by clicking on the blank area, hide the soft keyboard.

Android Click to close the soft keyboard

In the project, the EditText will automatically eject the soft keyboard when the focus is taken, and when you close it, you usually need to press the back key or click the button on the soft keyboard.

Even if the current activity has been completed, the soft keyboard still exists, affecting the user's experience.

Online There are many very detailed methods, such as clicking on other blank areas, the soft keyboard will disappear and the like, we do not require this project, the requirements are as long as

Do not block other operations, and the current activity is closed after the soft keyboard disappears on the line,

Today we share two ways:

?

//This method, if the display is hidden, if hidden then display private void hintkbone () { inputmethodmanager IMM = (Inputmethodmanager) getactivity (). Getsystemservice ( Context.input_method_service);    //get Inputmethodmanager instance if (imm.isactive ()) {   //if you turn on imm.togglesoftinput (inputmethodmanager.show_implicit, Inputmethodmanager.hide_not_always);                 } }

?

123456789

//此方法只是关闭软键盘private void hintKbTwo() { InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);             if(imm.isActive()&&getCurrentFocus()!=null){    if (getCurrentFocus().getWindowToken()!=null) {    imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);    }              }}

Just call the method when you need to click on the event to close the soft keyboard.
