Question

我在userdialog中有3个edittext，动态设置它们。其中2个正确键入文本，但1在某些设备上没有（android 2.3.4）。已经尝试过来自EditText freezes/doesn't show text whilst typing的解决方案。

这是我的代码：

    AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
    alertDialog.setTitle("Имя устройства");
    LinearLayout layout = new LinearLayout(context);


    //alertDialog.setMessage("Задайте имя устройства");
    final EditText inputName = new EditText(MainActivity.this); 
    inputName.setInputType(InputType.TYPE_CLASS_TEXT);
    inputName.setOnEditorActionListener(doneListener);

    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(
                          LinearLayout.LayoutParams.MATCH_PARENT,
                          LinearLayout.LayoutParams.MATCH_PARENT);
    layout.setOrientation(LinearLayout.VERTICAL);
    lp.setMargins(20, 20, 20, 20);
    layout.setLayoutParams(lp);


    final EditText inputInv = new EditText(MainActivity.this);
    inputInv.setInputType(InputType.TYPE_CLASS_NUMBER);
    inputInv.setTextColor(Color.BLACK);
    inputInv.setOnEditorActionListener(doneListener);


    final EditText inputDepartment = new EditText(MainActivity.this);
    inputDepartment.setInputType(InputType.TYPE_CLASS_TEXT);
    inputDepartment.setOnEditorActionListener(doneListener);

    final TextView name = new TextView(MainActivity.this); name.setText("Имя устройства"); //name.setLayoutParams(lp);
    final TextView inv = new TextView(MainActivity.this); inv.setText("Инвентарный номер"); //inv.setLayoutParams(lp);
    final TextView dep = new TextView(MainActivity.this); dep.setText("Департамент");// dep.setLayoutParams(lp);
    if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.GINGERBREAD_MR1) {
        name.setTextColor(Color.WHITE);
        inv.setTextColor(Color.WHITE);
        dep.setTextColor(Color.WHITE);
    }

    layout.addView(name);
    layout.addView(inputName);
    layout.addView(inv);
    layout.addView(inputInv);
    layout.addView(dep);
    layout.addView(inputDepartment);

    alertDialog.setView(layout);
    alertDialog.setPositiveButton("Продолжить",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,int which) {
                    SharedPreferences.Editor editor = shPref.edit();
                    String name = inputName.getText().toString() + "-" + inputInv.getText().toString() + "-" + inputDepartment.getText().toString();
                    editor.putString("Name", name);
                    editor.commit();
                    createShortCut(name);
                }
            });

    OnKeyListener okl = new OnKeyListener() {

         @Override
            public boolean onKey(DialogInterface arg0, int keyCode,
                    KeyEvent event) {
                if (keyCode == KeyEvent.KEYCODE_BACK) {
                    finish();
                    System.exit(0);
                }
                return true;
            }
        };

    alertDialog.setOnKeyListener(okl);
    alertDialog.show();

doneListener正在关闭软键盘。没有它也不行。

Answer 1

看起来像对话框中的一些软键盘的错误。通过拒绝对话框并使用Activity来解决此问题。

Android EditText不显示文字
