Android自定义扁平化对话框

  平时我们开发的大多数的Android、iOS的APP,它们的风格都是拟物化设计。如今Android 4.X、iOS 7、WP8采用的是扁平化设计,可以看出扁平化设计是未来UI设计的趋势。其实扁平化设计要比拟物化设计要简单一点,扁平化设计更加的简约,给人视觉上更加舒服。


  Shamoo想到在Android平台上弄一个扁平化的对话框。参考过一篇帖子,然后改了一下。

  这个Demo比较简单,首先是一个dialog的布局文件,这个dialog的布局要实例化成对话框可以通过AlertDialog.Builder的setView方法,将LayoutInflater实例化的dialog布局设置对话框具体显示内容。效果图如下:


  下面直接贴代码

  DialogWindows.java

 

package com.example.dialogwindows;

import android.net.Uri;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageButton;
import android.widget.ImageView;
import android.widget.Toast;

public class DialogWindows extends Activity {

	private Button button;
	private View dialogView;
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		button = (Button) findViewById(R.id.btn);
		button.setOnClickListener(new OnClickListener() {

			public void onClick(View v) {

				Builder builder = myBuilder(DialogWindows.this);
				final AlertDialog dialog = builder.show();
                //点击屏幕外侧,dialog不消失
				dialog.setCanceledOnTouchOutside(false);
				Button btnOK = (Button) dialogView.findViewById(R.id.btn_ok);
				btnOK.setOnClickListener(new OnClickListener() {
					public void onClick(View v) {
						Toast.makeText(DialogWindows.this, "你点击了确定按钮", Toast.LENGTH_SHORT).show();
						dialog.dismiss();
					}
				});
				Button btnCancel = (Button) dialogView.findViewById(R.id.btn_cancel);
				btnCancel.setOnClickListener(new OnClickListener() {
				public void onClick(View v) {
					Toast.makeText(DialogWindows.this, "你点击了取消按钮", Toast.LENGTH_SHORT).show();
					dialog.dismiss();
				}
			});
				ImageButton customviewtvimgCancel = (ImageButton) dialogView.findViewById(R.id.btn_exit);
				customviewtvimgCancel.setOnClickListener(new OnClickListener() {
					public void onClick(View v) {
						Toast.makeText(DialogWindows.this, "你点击了退出按钮", Toast.LENGTH_SHORT).show();
					    dialog.dismiss();
					}
				});
			}
		});
	}

	protected Builder myBuilder(Context context) {
		
		LayoutInflater inflater = getLayoutInflater();
		AlertDialog.Builder builder = new AlertDialog.Builder(context);
		dialogView = inflater.inflate(R.layout.dialog, null);
		return builder.setView(dialogView);
	}

}
