使用DialogFragment创建对话框总结

回调Activity中的函数

http://developer.android.com/guide/topics/ui/dialogs.html#PassingEvents

在DialogFragment中,定义Interface,然后在onAttach中绑定,最后在每个按钮的回调函数中调用Interface中定义的函数

在Activity中,实现Interface中定义的函数

Interface中定义的函数参数可以任意指定,因此可以用来在从DialogFragment向Activity传递参数

在DialogFragment中,直接在每个按钮的回调函数中调用Interface中定义的函数

在Activity中,实现Interface中定义的函数

Interface中定义的函数参数可以任意指定,因此可以用来在从DialogFragment向Activity传递参数

 

自定义Dialog界面,传递参数到Activity

使用OnCreateDialog()

第一种方法:

局部变量view需要声明为final

public class AllBonusDialogFragment extends DialogFragment {
public Dialog onCreateDialog(Bundle savedInstanceState) { AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); LayoutInflater inflater = getActivity().getLayoutInflater(); final View view = inflater.inflate(R.layout.input_dialog, null); builder.setView(view) .setPositiveButton("确定", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { EditText allBonusEdit = (EditText)view.findViewById(R.id.inputDialogEdit); String allBonusStr = allBonusEdit.getText().toString(); double allBonus = Double.parseDouble(allBonusStr); mListener.onDialogPositiveClick(allBonus); } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { mListener.onDialogNegativeClick(); } }); return builder.create(); }

第二种方法:

把view声明为成员变量

public class AllBonusDialogFragment extends DialogFragment {
    View view = null;
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        LayoutInflater inflater = getActivity().getLayoutInflater();
        view = inflater.inflate(R.layout.input_dialog, null);
        builder.setView(view)
               .setPositiveButton("确定", new PositiveOnClickListener())
               .setNegativeButton("取消", new NegativeOnClickListener());
        return builder.create();
    }
    
    class PositiveOnClickListener implements DialogInterface.OnClickListener {
	@Override
	public void onClick(DialogInterface dialog, int which) {
	    EditText allBonusEdit = (EditText)view.findViewById(R.id.inputDialogEdit);
            String allBonusStr = allBonusEdit.getText().toString();
            double allBonus = Double.parseDouble(allBonusStr);
            mListener.onDialogPositiveClick(allBonus);
        }
    }
    
    class NegativeOnClickListener implements DialogInterface.OnClickListener {
	@Override
	public void onClick(DialogInterface dialog, int which) {
	    mListener.onDialogNegativeClick();
        }
    }

使用OnCreateView()
