The perfect solution for Android development soft keyboard to block the login button

On the application login page we need to fill in the username and password. When filling in this information, the soft keyboard will block the login button, which makes the user experience poor, so we will solve this problem today

1: The login layout interface is as follows

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Things to note Yes:

ScrollView,

Button

2: Configure the activity in AndroidManifest.xml Android:windowSoftInputMode="stateHidden|adjustResize"

3: Look at the following code

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) { 
}; 
};
