java代码

package com.example.admin.keyboarddemo;import android.content.Context;import android.os.Bundle;import android.support.design.widget.FloatingActionButton;import android.support.design.widget.Snackbar;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.Toolbar;import android.view.View;import android.view.inputmethod.InputMethodManager;public class BaseActivity extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);}/** * @Description: 隐藏软键盘 */protected void hideInputMethod(){    final View view = getCurrentFocus();    if(view != null){        MainActivity.getMainHandler().postDelayed(new Runnable() {            @Override            public void run() {                ((InputMethodManager) getSystemService(INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(view.getWindowToken(),0);            }        },500);    }}/** * @Description:显示软键盘 */protected void showInputMethod(){    View view = getCurrentFocus();    if (view != null) {        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);        imm.showSoftInput(view, InputMethodManager.SHOW_FORCED);    }}}package com.example.admin.keyboarddemo;import android.os.Handler;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.view.MotionEvent;import android.view.View;import android.widget.Button;public class MainActivity extends BaseActivity implements View.OnClickListener {private Button btn;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    btn = (Button) findViewById(R.id.btn_text);    btn.setOnClickListener(this);}public static Handler getMainHandler(){    Handler handler = new Handler();    return handler;}@Overridepublic boolean onTouchEvent(MotionEvent event) {    if (getCurrentFocus() != null) {        hideInputMethod();    }    return super.onTouchEvent(event);}@Overridepublic void onClick(View v) {    hideInputMethod();}}

注：

所有继承BaseActivity,并且重写onTouchEvent（）方法，在方法中调用hideInputMethod()方法的Avtivity都能实现点击空白区域隐藏软件盘。showInputMethod（）为显示软键盘的方法，使用同上。
