你有什么想法，什么是错的？谢谢！！

UPDATE

我有点累了昨天，我并没有看到很多认为..
感谢您的意见！
所以，我重写的LinearLayout部分，我做了一些改动java文件，但我仍然有一些问题：

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/linear1" 

    android:gravity="center_vertical" 
    android:orientation="horizontal" 
    android:visibility="invisible" 

    android:layout_marginBottom="160dp" 
    android:layout_gravity="bottom|end" 
    android:layout_marginRight="@dimen/fab_margin"> 

<TextView 
    android:text="TextView" 
    android:layout_width="70dp" 
    android:layout_height="15dp" 
    android:id="@+id/textView3" 
    android:layout_weight="1" /> 

<android.support.design.widget.FloatingActionButton 
    android:id="@+id/fab2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    app:backgroundTint="@color/colorFAB2" 
    app:elevation="6dp" 
    app:pressedTranslationZ="12dp" 
    android:src="@android:drawable/ic_lock_silent_mode" /> 

</LinearLayout> 

，并在java文件：

public class MainActivity extends AppCompatActivity implement View.OnClickListener{ 
private Boolean isFabOpen = false; 
private FloatingActionButton fab,fab1,fab2; 
private Animation fab_open,fab_close,rotate_forward,rotate_backward; 
LinearLayout linear1; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    fab = (FloatingActionButton)findViewById(R.id.fab); 
    fab1 = (FloatingActionButton)findViewById(R.id.fab1); 
    fab2 = (FloatingActionButton)findViewById(R.id.fab2); 

    linear1 = (LinearLayout)findViewById(R.id.linear1); 

    fab_open = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fab_open); 
    fab_close = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.fab_close); 
    rotate_forward = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.rotate_forward); 
    rotate_backward = AnimationUtils.loadAnimation(getApplicationContext(),R.anim.rotate_backward); 
    fab.setOnClickListener(this); 
    fab1.setOnClickListener(this); 
    fab2.setOnClickListener(this); 
    linear1.setOnClickListener(this); 
} 

public void onClick(View v) { 
    int id = v.getId(); 
    switch (id){ 
     case R.id.fab: 

      animateFAB(); 
      break; 
     case R.id.fab1: 

      Log.d("Raj", "Fab 1"); 
      break; 
     case R.id.fab2: 

      Log.d("Raj", "Fab 2"); 
      break; 
    } 
} 

public void animateFAB(){ 

    if(isFabOpen){ 

     fab.startAnimation(rotate_backward); 
     fab1.startAnimation(fab_close); 
     linear1.startAnimation(fab_close); 
     fab1.setClickable(false); 
     fab2.setClickable(false); 
     isFabOpen = false; 
     Log.d("Raj", "close"); 

    } else { 

     fab.startAnimation(rotate_forward); 
     fab1.startAnimation(fab_open); 
     linear1.startAnimation(fab_open); 
     fab1.setClickable(true); 
     fab2.setClickable(true); 
     isFabOpen = true; 
     Log.d("Raj","open"); 

    } 
} 
} 

and the screenshot after the changes is:

任何想法怎么回事？谢谢！！

Answer 1

也许是无关的，但是这似乎LinearLayout错误：

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 

    android:gravity="center_vertical" 
    android:orientation="horizontal" 
    android:visibility="invisible"> 

您有需要整个屏幕，没有ID的无形的看法，所以我想你不把它转化为可见的后期。
