它很容易，請按照下面的教程使用警告對話框生成器來實現多選擇選擇器實現多選擇選擇器：

簡而言之：
new AlertDialog.Builder(this)
.setTitle("Planets")
.setMultiChoiceItems(new String[]{"Mars", "Earth"}, new boolean[]{false, false}, new DialogSelectionClickHandler())
.setPositiveButton("OK", new DialogButtonClickHandler())
.create();

// null)).findViewById(R.id.tvDialogTitle)).setText("Hosts");
// Log.d("Dialog object",
// " static made dialog in checkbox--> "+((TextView)((RelativeLayout)getActivity().getLayoutInflater().inflate(R.layout.event_filter_title,
// null)).findViewById(R.id.tvDialogTitle)).getText());
final LayoutInflater inflater123 = (LayoutInflater) getActivity()
