Soft keyboard does not show when Activity starts

问题

I have added android:windowSoftInputMode="stateAlwaysVisible" to my Activity in AndroidManifest.xml and here's my layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <EditText android:id="@+id/EditText01" android:layout_width="wrap_content"
        android:layout_height="wrap_content"></EditText>
    <EditText android:id="@+id/EditText02" android:layout_width="wrap_content"
        android:layout_height="wrap_content"></EditText>
    <Button android:id="@+id/Button01" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:text="Send"></Button>
</LinearLayout>

When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts?

Thanks

solution 1 :

write following code inside onCreate() method of activity

InputMethodManager imm = (InputMethodManager)
    SearchActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);

if (imm != null){
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
}

solution 2 :

create following method and call from onCreate()

private void showVirturalKeyboard(){
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {
         @Override
         public void run() {
              InputMethodManager m = (InputMethodManager) SearchActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);

              if(m != null){
                // m.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
                m.toggleSoftInput(0, InputMethodManager.SHOW_IMPLICIT);
              } 
         }

    }, 100);         
}

Try adding this to the activities onCreate() method

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
