xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/md_white_1000"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"

Java中的使用代码：
public class SlideDateTimeActivity extends FragmentActivity {
@Bind(R.id.button)
Button button;
private SimpleDateFormat mFormatter = new SimpleDateFormat("MMMM dd yyyy hh:mm aa");
private Button mButton;
private SlideDateTimeListener listener = new SlideDateTimeListener() {
@Override
public void onDateTimeSet(Date date) {
Toast.makeText(SlideDateTimeActivity.this,
mFormatter.format(date), Toast.LENGTH_SHORT).show();
}
// Optional cancel listener
@Override
public void onDateTimeCancel() {
Toast.makeText(SlideDateTimeActivity.this,
"Canceled", Toast.LENGTH_SHORT).show();
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_slide_date_time_picker);
ButterKnife.bind(this);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new SlideDateTimePicker.Builder(getSupportFragmentManager())
.setListener(listener)
.setInitialDate(new Date())
//.setMinDate(minDate)
//.setMaxDate(maxDate)
//.setIs24HourTime(true)
//.setTheme(SlideDateTimePicker.HOLO_DARK)
//.setIndicatorColor(Color.parseColor("#990000"))
.build()
.show();
}
});
}
}

android:text="预览版目前已经包括Android Wear最新API，这些新API可以让开发者以语音的方式定制和扩展他们的通知。其提供的仿真器可用于预览包括方形和圆形可穿戴设备上出现的通知方式，与此同时，谷歌也希望在未来几个月内继续为Android Wear设备提供新的API和功能。" />
<me.biubiubiu.justifytext.library.JustifyTextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/margin_20"
android:text="Tests whether this string matches the given regularExpression. This method returns true only if the regular expression matches the entire input string. A common mistake is to assume that this method behaves like contains(CharSequence); if you want to match anywhere within the input string, you need to add .* to the beginning and end of your regular expression. See matches(String, CharSequence)." />
</LinearLayout>3、android-shapeLoadingView实现高仿新版58 加载动画
效果图：
项目在GitHub上的地址：
https://github.com/zzz40500/android-shapeLoadingView项目使用：
