软键盘遮挡

本文主要是介绍软键盘遮挡，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在应用登陆页面我们需要填写用户名和密码。当填写这些信息的时候，软键盘会遮挡登陆按钮，这使得用户体验较差，所以今天就来解决这个问题

1：登陆布局界面如下

             android:text="登 录"  
             android:textColor="@color/white"  
             android:textSize="20sp" />  
     </LinearLayout>  
    
 </RelativeLayout>  

需要注意的是：

1：层级关系

RelativeLayout-----

LinearLayout----

ScrollView,

Button

2：在AndroidManifest.xml中的该activity配置 android:windowSoftInputMode="stateHidden|adjustResize"

3：看如下代码

[java]  view plain copy print ?  
 etAccount = (EditText) this.findViewById(R.id.sms_login_et_accout);  
         etAccount.setOnClickListener(this);  
         etAccount.setOnTouchListener(new OnTouchListener() {  
             @Override  
             public boolean onTouch(View v, MotionEvent event) {  
                 changeScrollView();   
                 return false;  
             }  
         });  
     /** 
      * 使ScrollView指向底部 
      */  
     private void changeScrollView(){  
         h.postDelayed(new Runnable() {  
             @Override  
             public void run() {  
                 sl_center.scrollTo(0, sl_center.getHeight());   
             }  
         }, 300);  
     }  
       
     Handler h = new Handler(){  
         public void handleMessage(Message msg) {  
         };  
     };
