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); } }
