Dialog总结

AlertDialog.Builder  AlertDialog   Dialog辨析

Dialog implements DialogInterface, Window.Callback, KeyEvent.Callback, OnCreateContextMenuListener, window.OnWindowDismissedCallback

AlertDialog extends Dialog implements DialogInterface {

     public static class Builder {}

}

一，谷歌建议使用之类 AlertDialog   ，不建议直接使用Dialog 。

二， AlertDialog.Builder 是 用来创建 AlertDialog  ， 并简化设置参数的工具类，可直接用连续的"."符号设置参数。

如：

        AlertDialog.Builder builder = new AlertDialog.Builder(this);

        TextView tv = new TextView(builder.getContext());

        tv.setText("haha");

        builder.setTitle("aaa")

                .setView(tv)

                .show();

AlertDialog.Builder 的api

1. /**
2. * Creates an {@link AlertDialog} with the arguments supplied to this
3. * builder.
4. * <p>
5. * Calling this method does not display the dialog. If no additional
6. * processing is needed, {@link #show()} may be called instead to both
7. * create and display the dialog.
8. */
9. public AlertDialog create() {
10. // Context has already been wrapped with the appropriate theme.
11. final AlertDialog dialog = new AlertDialog(P.mContext, 0, false);
12. P.apply(dialog.mAlert);
13. dialog.setCancelable(P.mCancelable);
14. if (P.mCancelable) {
15. dialog.setCanceledOnTouchOutside(true);
16. }
17. dialog.setOnCancelListener(P.mOnCancelListener);
18. dialog.setOnDismissListener(P.mOnDismissListener);
19. if (P.mOnKeyListener != null) {
20. dialog.setOnKeyListener(P.mOnKeyListener);
21. }
22. return dialog;
23. }

1. /**
2. * Creates an {@link AlertDialog} with the arguments supplied to this
3. * builder and immediately displays the dialog.
4. * <p>
5. * Calling this method is functionally identical to:
6. * <pre>
7. * AlertDialog dialog = builder.create();
8. * dialog.show();
9. * </pre>
10. */
11. public AlertDialog show() {
12. final AlertDialog dialog = create();
13. dialog.show();
14. return dialog;
15. }

半自定义Dialog View的两种方法

注：并非自定义view，而是利用Dialog本身提供的api进行自定义。

AlertDialog

1. public static void showSimpleDialog(Context context, String msg, View.OnClickListener listener) {
2. final AlertDialog.Builder builder = new AlertDialog.Builder(context);
3. final AlertDialog dialog = builder.create();
5. LayoutInflater inflater = LayoutInflater.from(context);
6. View view = inflater.inflate(R.layout.dialog_simple_deposit, null);
7. TextView tvConfirm = (TextView) view.findViewById(R.id.tv_confirm);
8. tvConfirm.setOnClickListener(listener);
9. tvConfirm.setOnClickListener(new View.OnClickListener() {
10. @Override
11. public void onClick(View v) {
12. dialog.dismiss();
13. }
14. });
15. TextView tvMsg = (TextView) view.findViewById(R.id.tv_msg);
16. tvMsg.setText(msg);
18. dialog.setView(view);
19. dialog.setCancelable(false);// 返回键不可取消
20. dialog.setView(view, 0, 0, 0, 0);// 可消除部分边框，当不能全部消除
21. dialog.show();
22. }

--------------------------------------

Dialog

1. public static void showSimpleDialog1(Context context, String msg) {
2. final Dialog dialog =new Dialog(context, R.style.dialog);// 可以消除黑色边框
4. LayoutInflater inflater = LayoutInflater.from(context);
5. View view = inflater.inflate(R.layout.dialog_simple_deposit, null);
6. TextView tvConfirm = (TextView) view.findViewById(R.id.tv_confirm);
7. // tvConfirm.setOnClickListener(listener);
8. tvConfirm.setOnClickListener(new View.OnClickListener() {
9. @Override
10. public void onClick(View v) {
11. dialog.dismiss();
12. }
13. });
14. TextView tvMsg = (TextView) view.findViewById(R.id.tv_msg);
15. tvMsg.setText(msg);
17. dialog.setContentView(view);
18. dialog.setCancelable(false);// 返回键不可取消
19. dialog.show();
20. }

1. <style name="dialog" parent="@android:style/Theme.Dialog">
