我在我的应用程序中添加了Bottomsheet.ii工作正常,但唯一的问题是它覆盖的额外空间,我只想删除Bottomsheet布局顶部的那些额外空格。
我想删除突出显示的部分:
我如何删除这些额外的空格?
这是我的XML
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:id="@+id/coordinatorLayout"
tools:context=".MainActivity">
<include layout="@layout/content_main" />
<LinearLayout

android:src="@drawable/ic_video"
android:layout_width="@dimen/fifty"
android:layout_height="@dimen/fifty" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
这是我的Java代码
public class MainActivity extends AppCompatActivity {
BottomSheetBehavior behavior;
View bottomSheet;
CoordinatorLayout coordinatorLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
coordinatorLayout = (CoordinatorLayout) findViewById(R.id.coordinatorLayout);
bottomSheet = findViewById(R.id.bottom_sheet);
behavior = BottomSheetBehavior.from(bottomSheet);
behavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
// React to state change
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
// React to dragging events
}
});
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
behavior.setState(BottomSheetBehavior.STATE_EXPANDED);
}
});
}
// Snackbar.make(coordinatorLayout,item + " is selected", Snackbar.LENGTH_LONG).setAction("Action", null).show();
// behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
if (ev.getAction() == MotionEvent.ACTION_DOWN) {
if (behavior.getState()==BottomSheetBehavior.STATE_EXPANDED) {
Rect outRect = new Rect();
bottomSheet.getGlobalVisibleRect(outRect);
if(!outRect.contains((int)ev.getRawX(), (int)ev.getRawY()))
behavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
}
return super.dispatchTouchEvent(ev);
}
}

我想我已经得到了答案。只需要从bottom_sheet中删除android:fitsSystemWindows="true"
,即LinearLayout。
以防我将xml代码放在下面。
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:id="@+id/coordinatorLayout"
tools:context=".MainActivity">
<include layout="@layout/content_main" />
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="horizontal"
app:behavior_hideable="true"
app:behavior_peekHeight="0dp"
android:id="@+id/bottom_sheet"
android:background="@android:color/holo_orange_light"
app:layout_behavior="@string/bottom_sheet_behavior"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:layout_weight="1"
android:layout_margin="@dimen/five"
android:padding="@dimen/ten"

<ImageView

android:layout_margin="@dimen/five"
android:padding="@dimen/ten"
android:src="@drawable/ic_image_gallery"
android:layout_width="@dimen/fifty"
android:layout_height="@dimen/fifty" />
<ImageView
android:layout_weight="1"
android:layout_margin="@dimen/five"
android:padding="@dimen/ten"
android:src="@drawable/ic_video_camera"
android:layout_width="@dimen/fifty"
android:layout_height="@dimen/fifty" />
<ImageView
android:layout_weight="1"
android:layout_margin="@dimen/five"
android:padding="@dimen/ten"
android:src="@drawable/ic_video_camera"
android:layout_width="@dimen/fifty"
android:layout_height="@dimen/fifty" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
仅仅供我使用,我使用了不同的drawable你需要将它改回原来的。
希望它有所帮助!

尝试使用CoordinatorLayout
和另外一个属性LinearLayout
更改android:orientation="vertical"
并再次运行。
答案 2 :(得分:0)
android:fitsSystemWindows="false"
会起作用!
