Android常用代码记录

1.获得 RadioButton值

[java]
rb1 = (RadioButton)findViewById(R.id.sex1);
if (rb1.isChecked())
{
sex = "M";
} else
{
sex = "F";
}

2.两个Activity间传递数据
[java]
发送方:

       Intent intent = new Intent();
       intent.setClass(EX03_11.this,EX03_11_1.class);

       Bundle bundle = new Bundle();
       bundle.putDouble("height", height);
       bundle.putString("sex", sex);
       intent.putExtras(bundle);
//打开另一个activity
       startActivityForResult(intent, 0);
接受方:
    intent =this.getIntent();
    bundle=intent.getExtras();
    String sex =bundle.getString("sex");
    double height =bundle.getDouble("height");

3.打开一个消息框
[java]
new AlertDialog.Builder(EX03_12.this)
   .setTitle(R.string.app_about)
   .setMessage(R.string.app_about_msg)
   .setPositiveButton(R.string.str_ok,
       newDialogInterface.OnClickListener()
       {
         publicvoid onClick(DialogInterface dialoginterface, int i)
         {
         } www.zzzyk.com
       }).show();

4.改变文本框的字体
mText.setTypeface(Typeface.createFromAsset(getAssets(),
"fonts/HandmadeTypewriter.ttf"));
注: 在assets目录下建立fonts文件夹并放入HandmadeTypewriter.ttf字体文件
