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

 /**
         * Creates an {@link AlertDialog} with the arguments supplied to this
         * builder.
         * <p>
         * Calling this method does not display the dialog. If no additional
         * processing is needed, {@link #show()} may be called instead to both
         * create and display the dialog.
         */
        public AlertDialog create() {
            // Context has already been wrapped with the appropriate theme.
            final AlertDialog dialog = new AlertDialog(P.mContext, 0, false);
            P.apply(dialog.mAlert);
            dialog.setCancelable(P.mCancelable);
            if (P.mCancelable) {
                dialog.setCanceledOnTouchOutside(true);
            }
            dialog.setOnCancelListener(P.mOnCancelListener);
            dialog.setOnDismissListener(P.mOnDismissListener);
            if (P.mOnKeyListener != null) {
                dialog.setOnKeyListener(P.mOnKeyListener);
            }
            return dialog;
        }

/**
         * Creates an {@link AlertDialog} with the arguments supplied to this
         * builder and immediately displays the dialog.
         * <p>
         * Calling this method is functionally identical to:
         * <pre>
         *     AlertDialog dialog = builder.create();
         *     dialog.show();
         * </pre>
         */
        public AlertDialog show() {
            final AlertDialog dialog = create();
            dialog.show();
            return dialog;
        }

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

    public static void showSimpleDialog(Context context, String msg, View.OnClickListener listener) {
        final AlertDialog.Builder builder = new AlertDialog.Builder(context);
        final AlertDialog dialog = builder.create();
        LayoutInflater inflater = LayoutInflater.from(context);
        View view = inflater.inflate(R.layout.dialog_simple_deposit, null);
        TextView tvConfirm = (TextView) view.findViewById(R.id.tv_confirm);
        tvConfirm.setOnClickListener(listener);
        tvConfirm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        TextView tvMsg = (TextView) view.findViewById(R.id.tv_msg);
        tvMsg.setText(msg);
        dialog.setView(view);
        dialog.setCancelable(false);// 返回键不可取消
        dialog.setView(view, 0, 0, 0, 0);// 可消除部分边框，当不能全部消除
        dialog.show();
    }

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

Dialog

    public static void showSimpleDialog1(Context context, String msg) {
        final Dialog dialog =new Dialog(context, R.style.dialog);// 可以消除黑色边框
        LayoutInflater inflater = LayoutInflater.from(context);
        View view = inflater.inflate(R.layout.dialog_simple_deposit, null);
        TextView tvConfirm = (TextView) view.findViewById(R.id.tv_confirm);
//        tvConfirm.setOnClickListener(listener);
        tvConfirm.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });
        TextView tvMsg = (TextView) view.findViewById(R.id.tv_msg);
        tvMsg.setText(msg);
        dialog.setContentView(view);
        dialog.setCancelable(false);// 返回键不可取消
        dialog.show();
    }

        <item name="android:windowFrame">@null</item>
