## 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();`
4.  ``
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);`
17. ``
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`
3.  ``
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);`
16. ``
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">`
2.  `<item name="android:windowFrame">@null</item>`
3.  `<item name="android:windowIsFloating">true</item>`
4.  `<item name="android:windowIsTranslucent">true</item>`
5.  `<item name="android:windowNoTitle">true</item>`
6.  `<item name="android:background">@android:color/transparent</item>`
7.  `<item name="android:windowBackground">@android:color/transparent</item>`
8.  `<item name="android:backgroundDimEnabled">true</item>`
9.  `<item name="android:backgroundDimAmount">0.6</item>`
10. `</style>`
