Android自定义Dialog(美化界面)

前言:在做项目的时候,发现dialog界面太丑陋,从csdn上下载了一份自定义dialog的源码,在他的基础上对界面进行美化...有需要的朋友可以直接拿走

效果图如下：

主要代码:

/**

public class CustomDialog extends Dialog {
    public CustomDialog(Context context) {
        super(context);
    }

    public CustomDialog(Context context, int theme) {
        super(context, theme);
    }

    public static class Builder {
        private Context context;
        private String title;
        private String message;
        private String positiveButtonText;
        private String negativeButtonText;
        private View contentView;
        private DialogInterface.OnClickListener positiveButtonClickListener;
        private DialogInterface.OnClickListener negativeButtonClickListener;

        public Builder(Context context) {
            this.context = context;
        }

        public Builder setMessage(String message) {
            this.message = message;
            return this;
        }

        /**
         * Set the Dialog message from resource
         * @param title
         * @return
         */
        public Builder setMessage(int message) {
            this.message = (String) context.getText(message);
            return this;
        }

        /**
         * Set the Dialog title from resource
         * @param title
         * @return
         */
        public Builder setTitle(int title) {
            this.title = (String) context.getText(title);
            return this;
        }

        /**
         * Set the Dialog title from String
         * @param title
         * @return
         */

        public Builder setTitle(String title) {
            this.title = title;
            return this;
        }

        public Builder setContentView(View v) {
            this.contentView = v;
            return this;
        }

        /**
         * Set the positive button resource and it's listener
         * @param positiveButtonText
         * @return
         */
        public Builder setPositiveButton(int positiveButtonText,
                DialogInterface.OnClickListener listener) {
            this.positiveButtonText = (String) context
                    .getText(positiveButtonText);
            this.positiveButtonClickListener = listener;
            return this;
        }

        public Builder setPositiveButton(String positiveButtonText,
                DialogInterface.OnClickListener listener) {
            this.positiveButtonText = positiveButtonText;
            this.positiveButtonClickListener = listener;
            return this;
        }

        public Builder setNegativeButton(int negativeButtonText,
                DialogInterface.OnClickListener listener) {
            this.negativeButtonText = (String) context
                    .getText(negativeButtonText);
            this.negativeButtonClickListener = listener;
            return this;
        }

        public Builder setNegativeButton(String negativeButtonText,
                DialogInterface.OnClickListener listener) {
            this.negativeButtonText = negativeButtonText;
            this.negativeButtonClickListener = listener;
            return this;
        }

        //创建dialog对象   主要就是这个方法,加载自定义布局文件
        public CustomDialog create() {
            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            // instantiate the dialog with the custom Theme
            final CustomDialog dialog = new CustomDialog(context,
                    R.style.Dialog);
            View layout = inflater.inflate(R.layout.dialog_normal_layout, null);
            dialog.addContentView(layout, new LayoutParams(
                    LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
            // set the dialog title
            ((TextView) layout.findViewById(R.id.title)).setText(title);
            // set the confirm button
            if (positiveButtonText != null) {
                ((Button) layout.findViewById(R.id.positiveButton))
                        .setText(positiveButtonText);
                if (positiveButtonClickListener != null) {
                    ((Button) layout.findViewById(R.id.positiveButton))
                            .setOnClickListener(new View.OnClickListener() {
                                public void onClick(View v) {
                                    positiveButtonClickListener.onClick(dialog,
                                            DialogInterface.BUTTON_POSITIVE);
                                }
                            });
                }
            } else {
                // if no confirm button just set the visibility to GONE
                layout.findViewById(R.id.positiveButton).setVisibility(
                        View.GONE);
            }
            // set the cancel button
            if (negativeButtonText != null) {
                ((Button) layout.findViewById(R.id.negativeButton))
                        .setText(negativeButtonText);
                if (negativeButtonClickListener != null) {
                    ((Button) layout.findViewById(R.id.negativeButton))
                            .setOnClickListener(new View.OnClickListener() {
                                public void onClick(View v) {
                                    negativeButtonClickListener.onClick(dialog,
                                            DialogInterface.BUTTON_NEGATIVE);
                                }
                            });
                }
            } else {
                // if no confirm button just set the visibility to GONE
                layout.findViewById(R.id.negativeButton).setVisibility(
                        View.GONE);
            }
            // set the content message
            if (message != null) {
                ((TextView) layout.findViewById(R.id.message)).setText(message);
            } else if (contentView != null) {
                ((LinearLayout) layout.findViewById(R.id.content))
                        .removeAllViews();
                ((LinearLayout) layout.findViewById(R.id.content)).addView(
                        contentView, new LayoutParams(LayoutParams.FILL_PARENT,
                                LayoutParams.FILL_PARENT));
            }
            dialog.setContentView(layout);
            return dialog;
        }

    }
}

4.Activity中如何调用:

CustomDialog.Builder builder = new CustomDialog.Builder(this);
builder.setMessage("这个就是自定义的提示框");
builder.setTitle("提示");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        dialog.dismiss();
        //设置你的操作事项
    }
});

builder.setNegativeButton("取消",
        new android.content.DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

builder.create().show();
