学习札记-Android的对话框

以下代码在android SDK 2.2中测试过。

?

可选列表对话框：

	private void testItemDialog(){		AlertDialog.Builder builder = new AlertDialog.Builder(this);		builder.setTitle("Select a color");		final String[] items = {"blue","red","green"};		builder.setItems(items, new DialogInterface.OnClickListener(){			@Override			public void onClick(DialogInterface dialog, int which) {				// TODO Auto-generated method stub				Toast.makeText(getApplicationContext(), items[which], Toast.LENGTH_SHORT).show();			}		}).create().show();	}

带Check box的列表对话框：

	private void testItemDialog(){		AlertDialog.Builder builder = new AlertDialog.Builder(this);		builder.setTitle("Select a color");		final String[] items = {"blue","red","green"};		builder.setSingleChoiceItems(items, -1, new DialogInterface.OnClickListener(){			@Override			public void onClick(DialogInterface dialog, int which) {				Toast.makeText(getApplicationContext(), items[which], Toast.LENGTH_SHORT).show();			}			}).create().show();	}

?

带进度条的对话框(圆圈状，没有百份比的那种)：

private void testProgressDialog(){		ProgressDialog dialog = ProgressDialog.show(this, "", "Loading. Please wait...");	}

?带进度条的对话框(圆圈状，显示百份比的那种)：
