java Force在AlertDialog中显示软键盘

Question

我有以下代码，我认为这些代码可以在显示警报对话框时强制显示键盘

public void showTypeBox(){
        edit = new EditText(this);
        edit.setPadding(10, 0, 0, 10);

        AlertDialog dialog = new AlertDialog.Builder(this)
            .setTitle("Type word to search for:")
            .setPositiveButton("Search", Main.this)
            .setNegativeButton("Cancel", null)
            .setView(edit)
            .setIcon(R.drawable.menu_icon)
            .create();
        dialog.show();

        InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        mgr.showSoftInput(edit, InputMethodManager.SHOW_IMPLICIT);
    }

我看不出我做错了什么

Answer 1

您试图在EditText布局并可见之前显示键盘。试试这个：

Handler delayedRun = new Handler();
delayedRun.post(new Runnable() {
  @Override
  public void run() {
    edit.requestFocus();
    InputMethodManager mgr = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
    mgr.showSoftInput(addressBox, InputMethodManager.SHOW_IMPLICIT);
  }
});
