SearchView窗口小部件文本未与工具栏的左/左对齐

Question

我正在SearchView中实现Activity。一切正常，但文本开始或对齐到中心而不是向左对齐。

下面是xml代码

search_toolbar.xml

<item
    android:id="@+id/m_search"
    android:icon="@drawable/ic_search"
    android:title=""
    android:visible="true"
    app:actionViewClass="android.support.v7.widget.SearchView"
    app:showAsAction="ifRoom|collapseActionView" />

在主要活动中，我定义了回调，这些回调用于片段中以基于查询刷新数据。

主要活动代码

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.search_toolbar, menu);
    MenuItem item = menu.findItem(R.id.m_search);
    MenuItemCompat.setOnActionExpandListener(item, new MenuItemCompat.OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            // Called when SearchView is collapsing
            if (item.isActionViewExpanded()) {
                animateSearchToolbar(1, false, false);
                toolbar_title.setVisibility(View.VISIBLE);
            }
            return true;
        }

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            // Called when SearchView is expanding
            toolbar_title.setVisibility(View.GONE);
            animateSearchToolbar(1, true, true);
            return true;
        }
    });
    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    final SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.m_search));
    searchView.setGravity(Gravity.START);
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            Log.w(TAG, "onQueryTextSubmit : " + query);
            if (!TextUtils.isEmpty(query)) {
                callback.searchQuery(query);
            }
            hideKeyboard();
            return true;
        }

        @Override
        public boolean onQueryTextChange(String s) {
            Log.w(TAG, "onQueryTextChange : " + s);
            if (TextUtils.isEmpty(s)) {
                hideKeyboard();
                callback.refreshData();
            }
            return false;
        }
    });
    searchView.setOnCloseListener(new SearchView.OnCloseListener() {
        @Override
        public boolean onClose() {
            Log.w(TAG, "OnCloseListener : ");
            return false;
        }
    });
    searchView.setOnSearchClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Log.w(TAG, "OnSearchClickListener : ");
        }
    });
    return true;
}

这是main_activity.xml

Answer 1

尝试更改

searchView.setGravity(Gravity.START);

对于

searchView.setGravity(Gravity.LEFT);
