android各种对话框总结笔记

确定取消对话框（带图标）

						//（上下文，主题）
new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT)
    .setTitle("标题").setMessage("内容").setIcon(R.drawable.ic_launcher)
								//响应点击事件
    .setPositiveButton("确定", new OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            // TODO Auto-generated method stub
            Toast.makeText(MainActivity.this, "确定", 0).show();
        }
    }).setNegativeButton("取消", null).show();//别忘了show出来

效果

简单单选对话框

final String[] strs=new String[]{"男","女","不告诉你"};
new AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT)
		.setTitle("标题").setIcon(R.drawable.ic_launcher)
							//（String数组，默认选择项，响应事件）
		.setSingleChoiceItems(strs, 2, new OnClickListener() {
			//swich:所选项的数组id
			@Override
			public void onClick(DialogInterface dialog, int which) {
				// TODO Auto-generated method stub
				Toast.makeText(MainActivity.this, strs[which], 0).show();
			}
		})
		.show();

效果

多选对话框

final String[] strs = new String[] { "香蕉", "苹果", "梨子" };
    AlertDialog.Builder dialog = new AlertDialog.Builder(this,
            AlertDialog.THEME_DEVICE_DEFAULT_LIGHT).setTitle("标题")
            .setIcon(R.drawable.ic_launcher)
            .setMultiChoiceItems(strs, new boolean[]{true,true,false}, new OnMultiChoiceClickListener() {
                //which:所选项的数组id
				//isChecked:所选项的选中状态
                @Override
                public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                    // TODO Auto-generated method stub
                    Log.d("test", "which="+which+":isChecked="+isChecked);
                }
            });

    dialog.create().show();

效果

final ProgressDialog pd = new ProgressDialog(this);
    // 只有两种主题
    pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
	//设置最大进度值
    pd.setMax(100);
    pd.setTitle("标题");
    pd.setMessage("请捎到.....");
    pd.show();
    new Thread() {
        public void run() {
            for (int i = 1; i < 100; i++) {
                try {
                    Thread.sleep(100);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
                pd.setProgress(i);
            }
            // 在任何线程都可以关闭，
            pd.dismiss();
        };
    }.start();

                // TODO Auto-generated method stub
                Toast.makeText(MainActivity.this,
                        et_text.getText().toString(), 0).show();
            }
