隐藏AutoCompleteTextView键盘

Question

我的布局中有两个EditText和两个AutoCompleteTextView。但是我喜欢只为AutoCompleteTextView隐藏键盘。但是它没有隐藏键盘，当我触摸AutoCompleteTextView时，键盘仍然出现，我如何隐藏键盘？我实现为

final View addView = getLayoutInflater().inflate(R.layout.addnewtracker, null);                     
        final TrackerInfo newInfo = new TrackerInfo();          

        String[] type = {"Vehicle", "Person", "Pet", "Others"}; 
        final AutoCompleteTextView actvtype1 = (AutoCompleteTextView) addView.findViewById(R.id.autoCompleteTextView1);             
        ArrayAdapter<String> typeadapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_multiple_choice,type);          
        actvtype1.setThreshold(1);
        actvtype1.setAdapter(typeadapter);
        actvtype1.setTextColor(Color.BLACK);            

        String[] model = {"TS102", "TS103"};
        final AutoCompleteTextView actvtype2 = (AutoCompleteTextView) addView.findViewById(R.id.autoCompleteTextView2);
        ArrayAdapter<String> modeladapter = new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_multiple_choice,model);
        actvtype2.setThreshold(1);
        actvtype2.setAdapter(modeladapter);
        actvtype2.setTextColor(Color.BLACK);            

        final AlertDialog.Builder alert = new AlertDialog.Builder(this).setTitle("New Tracker").setView(addView);
        InputMethodManager keyboard = (InputMethodManager)
        getSystemService(Context.INPUT_METHOD_SERVICE);
        keyboard.hideSoftInputFromInputMethod(actvtype1.getWindowToken(), 0);
        keyboard.hideSoftInputFromInputMethod(actvtype2.getWindowToken(), 0); 
        alert.setPositiveButton("ADD", new DialogInterface.OnClickListener() 
        {


            @SuppressLint("SimpleDateFormat")
            public void onClick(DialogInterface dialog, int whichButton) 
            {                   


            }
        }).setNegativeButton("Cancel", null).show();

我的布局如下

<?xml version="1.0" encoding="utf-8"?>

Answer 1

我不确定这是否正是您要寻找的内容，但这是用来迫使键盘从屏幕底部弹出的代码：

actvtype1.setInputType(InputType.TYPE_NULL);

当您单击该TextView时，这肯定会阻止键盘出现。希望能帮上忙！

Answer 2

将重点放在自动文本上的请求如下：

   <AutoCompleteTextView
            android:id="@+id/autoCompleteTextView2"
                ..
                .../>
         <requestFocus />

然后使用以下代码：

 if(autocomplete.hasfocus()){
    hideSoftKeyboard();
    }


    private void hideSoftKeyboard() {
        if(getCurrentFocus()!=null && getCurrentFocus() instanceof EditText)
        {
             InputMethodManager imm =(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
             imm.hideSoftInputFromWindow(getWindow().getCurrentFocus().getWindowToken(), 0);
        }

     }

Answer 3

单击onItemClick中的列表项后隐藏键盘

public void onItemClick(AdapterView<?> adapterViewIn, View viewIn, int indexSelected, long arg3) {
     InputMethodManager imm = (InputMethodManager) getSystemService(viewIn.getContext().INPUT_METHOD_SERVICE);
     imm.hideSoftInputFromWindow(viewIn.getApplicationWindowToken(), 0);
     // whatever else should be done
}
