我有一个带有ActionView菜单项的ActionBar(使用ActionBarSherlock)，我可以在其中显示EditText作为搜索字段。这是在ActionBar中启动另一个带有Activity的CustomView的输入，它显示相同的布局(我不使用任何强制SoftKeyboard出现在第二个 Activity 中的方法，这里没有问题)。当我希望在第一次 Activity 中 View 折叠时使软键盘自动显示/消失时，我使用:

openKeyboard方法

mImm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);  

mImm.hideSoftInputFromWindow(edittext.getWindowToken(), 0); 

Menu (ActionView)

ActionBar actionBar;
MenuItem itemSearchAction;
EditText mSearchEdit;
InputMethodManager mImm;

@Override
public boolean onCreateOptionsMenu(final Menu menu) {
    getSupportMenuInflater().inflate(R.menu.main, menu);

    itemSearchAction = menu.findItem(R.id.action_search);
    View v = (View) itemSearchAction.getActionView();
    mSearchEdit = (EditText) v.findViewById(R.id.SearchEdit);
    itemSearchAction.setOnActionExpandListener(this);

    return true;
}  

OnActionExpandListener

@Override
public boolean onMenuItemActionExpand(MenuItem item) {
    actionBar.setIcon(R.drawable.ic_app_search); // change icon
    mSearchEdit.requestFocus(); // set focus on edittext
    openKeyboard(); // the method above
    mSearchEdit.setOnEditorActionListener(new OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_SEARCH || (event != null && event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) {
                closeKeyboard(); // same method as above
                // new Intent() to second activity 
                // perform with startActivity();
                itemSearchAction.collapseActionView(); // collapse view
                return true;
            }
            return false;
        }
    });
    // add a clicklistener to re-open the keyboard on lower versions
    mSearchEdit.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            openKeyboard();
        }  
    });
    return true;
}

@Override
public boolean onMenuItemActionCollapse(MenuItem item) {
    actionBar.setIcon(R.drawable.ic_app_logo); // change icon again
    if(!(mSearchEdit.getText().toString().equals("")))
                            mSearchEdit.setText(""); // reinitial the edittext
    return true;
}  

OnOptionsItemSelected

// I had this verification when I make new Intent() to  
// a new activity, just in case (works like a charm)  
if(itemSearchAction.isActionViewExpanded())
         itemSearchAction.collapseActionView();  

ActionView (Item + layout)

<item
     android:id="@+id/action_search"
     android:icon="@drawable/ic_app_search"
     android:title="@string/action_search"
     android:showAsAction="ifRoom|collapseActionView"
     android:actionLayout="@layout/search_actionview" />  

<EditText
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/SearchEdit"
     android:layout_width="fill_parent" android:layout_height="wrap_content"
     android:layout_gravity="right|bottom" android:gravity="left"
     android:layout_marginBottom="6dip"
     android:hint="@string/action_search"
     android:textColor="@color/white"
     android:textColorHint="@color/white"
     android:singleLine="true"
     android:cursorVisible="true"
     android:inputType="text"
     android:imeOptions="actionSearch|flagNoExtractUi"
     android:imeActionLabel="@string/action_search"
     android:focusable="true" android:focusableInTouchMode="true"
     android:background="@drawable/bt_edit_searchview_focused" >

     <requestFocus />
</EditText>

int mode = WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE;
getWindow().setSoftInputMode(mode);  

postDelayed() to show: .showSoftInput(mSearchEdit, InputMethodManager.SHOW_IMPLICIT); - 200ms (Not working on lower versions)
postDelayed() to hide: .hideSoftInputFromWindow(mSearchEdit.getWindowToken(), 0); - 200ms  

new Runnable() on edittext => requestFocus() + showSoftInput(SHOW_IMPLICIT/FORCED/HIDE_NOT_ALWAYS/HIDE_IMPLICIT_ONLY)

// close the keyboard before intent
closeKeyboard();
// make the intent after 500 ms
Handler handler = new Handler();
Runnable runner = new Runnable() {
    public void run() {
        // new intent with startActivity()
    }
};
handler.postDelayed(runner, 500); 
// collapse the View  
itemSearchAction.collapseActionView();  

最佳答案

你尝试过这个吗？

setContentView(R.layout.activity_direction_3);
    getWindow().getDecorView().setBackgroundColor(
            android.R.color.transparent);

关于android - 当我返回到“Activity ”时，空间为空(强制使用软键盘)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20559963/
