android-keyboard 没有出现在 TabActivity 的子活动中

Question

代码sn-p：

public class home extends TabActivity implements OnTabChangeListener{

private static final String HOME_SPEC = "";
private static final String PROFILE_SPEC = "";
private static final String NEWPOST_SPEC = "";
private static final String SETTINGS_SPEC = "";
private TabHost tabHost; 
private TextView header;
int s,c;
private Typeface tf;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.home);

    tabHost = getTabHost();

    TabSpec newpostSpec = tabHost.newTabSpec(NEWPOST_SPEC);
    newpostSpec.setIndicator(NEWPOST_SPEC, getResources().getDrawable(R.drawable.icon_post_tab));
    Intent newpostIntent = new Intent(home.this,NewPostActivity.class);
    newpostSpec.setContent(newpostIntent);

    tabHost.addTab(loginSpec);
    tabHost.addTab(newpostSpec);

    tabHost.setOnTabChangedListener(this);
    for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
        {
            tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.TRANSPARENT);

        }

       }

    @Override
    public void onTabChanged(String tabId) {
        // TODO Auto-generated method stub
        for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
        {
            tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
        }

        tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.TRANSPARENT);
    }

}

上面的代码我用于 TabActivity。现在在 NewPostActivity 我只有一个编辑文本，当我点击 Edittext 时，键盘似乎没有写入该编辑文本。 那么键盘外观应该怎么做呢？ 请回复....

Answer 1

For showing the keyboard implicitly do like this

// for showing the soft keyboard on click of edit text
    InputMethodManager mgr = (InputMethodManager)     getSystemService(Context.INPUT_METHOD_SERVICE);
    // only will trigger it if no physical keyboard is open
    mgr.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);


and to hide the keyboard it when touched somewhere outside of the edit text.

rel.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            InputMethodManager mgr = (InputMethodManager)     getSystemService(Context.INPUT_METHOD_SERVICE);
            mgr.hideSoftInputFromWindow(editText.getWindowToken(), 0);
            return false;
        }
    });

这里rel是xml中的顶层布局
