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:

/**
 * 自定义dialog
 * @author ansen
 */
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();
