Android监听输入法的状态：弹起，关闭

1. 在根视图添加一个id，

   @+id=root_view

   ，如

   

2. 监听布局的状态

   @BindView(R.id.rl_rootview)
   FrameLayout frameLayout;
   
   frameLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
               @Override
               public void onGlobalLayout() {
                   if (isShowBoard) {
                       int heightDiff = frameLayout.getRootView().getHeight() - frameLayout.getHeight();
                       if (heightDiff > dpToPx(getActivity(), 200)) { // if more than 200 dp, it's probably a keyboard...
                           // ... do something here
                           Log.d("----------", "打开");
    
                       } else {
                           Log.d("----------", "关闭");
                          
                       }
                   }
               }
           });
   
   
    //dp转px
       public float dpToPx(Context context, float valueInDp) {
           DisplayMetrics metrics = context.getResources().getDisplayMetrics();
           return TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, valueInDp, metrics);
       }
              

3. 在

   manifest.xml

   中给activity设置

   windowSoftInputMode="adjustResize"

   <activity
       android:name=".activity.AddActivity"
       android:windowSoftInputMode="adjustResize"
       android:theme="@style/AppTheme.NoActionBar" />
