Question

我在操作栏中使用搜索字段，将其设置为名为search_layout.xml的布局文件夹中的xml。在2.3.3版本的android中，有一个问题，如搜索图标未显示在键盘中我输入文字后的第一次。相反，我必须单击“输入”键，然后单击文本字段，然后只显示“搜索”图标。这不会发生在更高版本，如4.0.4和4.4.2的android。

这是search_layout.xml：

此xml是参考res＆gt;＆gt; menu＆gt;＆gt; menu.xml

<item
    android:id="@+id/action_notification"
    android:actionLayout="@layout/search_layout"
    android:icon="@drawable/ic_searchicon"
    android:orderInCategory="0"
    android:showAsAction="always|collapseActionView"
    android:title="Search"/>

这是我在名为Activity_HomeScreen类的活动中使用的代码片段。

public boolean onCreateOptionsMenu(Menu menu) 
    {
        MenuInflater inflater = getSupportMenuInflater();
        inflater.inflate(R.menu.menu, menu);
        MenuItem itemListMap,itemRefresh;

        editsearch = (EditText) menu.findItem(R.id.action_notification).getActionView();
        editsearch.addTextChangedListener(textWatcher);
        editsearch.setOnEditorActionListener(new OnEditorActionListener() 
        {
            @Override
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) 
            {
                if (actionId == EditorInfo.IME_ACTION_SEARCH) 
                {
                    editsearch.clearFocus();
                    InputMethodManager imm = (InputMethodManager)Activity_HomeScreen.this.getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(editsearch.getWindowToken(), 0);
                    captureViepagerFragments(mVpContainer.getCurrentItem());
                }
                return false;
            }
        });
 MenuItem menuSearch = menu.findItem(R.id.action_notification);

        menuSearch.setOnActionExpandListener(new OnActionExpandListener() 
        {

            // Menu Action Collapse
            @Override
            public boolean onMenuItemActionCollapse(MenuItem item)
            {
                // Empty EditText to remove text filtering
                editsearch.setText("");
                editsearch.clearFocus();
                InputMethodManager imm = (InputMethodManager)Activity_HomeScreen.this.getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(editsearch.getWindowToken(), 0);
                captureViepagerFragments(mVpContainer.getCurrentItem());
                return true;
            }

            // Menu Action Expand
            @Override
            public boolean onMenuItemActionExpand(MenuItem item) 
            {
                // Focus on EditText
                editsearch.requestFocus();
                // Force the keyboard to show on EditText focus
                InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
                return true;
            }
        });


        return super.onCreateOptionsMenu(menu);
    }

通过这样做解决了这个问题：

            public boolean onMenuItemActionExpand(MenuItem item) 
            {
                editsearch.clearFocus();
                editsearch.post(new Runnable() {
                    @Override
                    public void run() {
                        editsearch.requestFocus();
                        final InputMethodManager imm = (InputMethodManager) Activity_Cat_Products.this
                                .getSystemService(Context.INPUT_METHOD_SERVICE);
                        imm.showSoftInput(editsearch, InputMethodManager.SHOW_IMPLICIT);

                    }
                });
                return true;
            }
