android自定義彈出框樣式實現

前言:

做專案時,感覺android自帶的彈出框樣式比較醜,很多應用都是自己做的彈出框,這裡也試著自己做了一個。

廢話不說先上圖片:


實現機制

1.先自定義一個彈出框的樣式

2.自己實現CustomDialog類,繼承自Dialog,實現裡面方法,在裡面載入自定義樣式的彈出框;

3.使用時,與使用Dialog一樣

具體程式碼

dialog_normal_layout.xml樣式檔案

自定義Dialog的實現類CustomDialog

package com.dyr.custom;

import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.Button;
import android.widget.LinearLayout;
import android.widget.TextView;

import com.dyr.view.R;

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

		 */
		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,

			return this;
		}

		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) {
				// if no message set
				// add the contentView to the dialog body
				((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;
		}
	}
}

使用程式碼

CustomDialog.Builder builder = new CustomDialog.Builder(this);
		builder.setMessage("這個就是自定義的提示框");
		builder.setTitle("提示");
		builder.setPositiveButton("確定", new DialogInterface.OnClickListener() {
			public void onClick(DialogInterface dialog, int which) {
				dialog.dismiss();
				//設定你的操作事項
			}
		});

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

		builder.create().show();

至此,自定義彈出框已經完成,是不是感覺很簡單呢。
