安卓第三天笔记--通知-进度条-时期

1.通知Notification

通知就是在是上方的状态栏弹出通知消息

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    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" >     <Button        android:onClick="send"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="发送通知" /> </RelativeLayout>

 <?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >       <TextView        android:id="@+id/tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:text="这是通知的跳转页面"/>     <ImageView        android:id="@+id/iv"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:src="@drawable/swift"/>   </LinearLayout>

2.TitleProgressBar

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="horizontal"     android:layout_width="match_parent"     android:layout_height="match_parent">     <Button         android:id="@+id/btn1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_horizontal"         android:text="显示"         />     <Button         android:id="@+id/btn2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_horizontal"         android:text="隐藏"         /></LinearLayout>

/** * 标题栏上方显示进度条     * @author 刘楠 * * 2016-2-19下午11:12:21 */public class MainActivity extends Activity {      private Button btn1;     private Button btn2;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);                 requestWindowFeature(Window.FEATURE_PROGRESS);                 //requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);         setContentView(R.layout.activity_main);                         btn1 = (Button) findViewById(R.id.btn1);         btn2 = (Button) findViewById(R.id.btn2);                 btn1.setOnClickListener(new OnClickListener()         {              @Override              public void onClick(View source)              {                   //显示不带进度的进度条                   setProgressBarIndeterminateVisibility(true);                   //显示带进度的进度条                   setProgressBarVisibility(true);                   //设置进度条的进度                   setProgress(4500);              }         });         btn2.setOnClickListener(new OnClickListener()         {              @Override              public void onClick(View source)              {                   //隐藏不带进度的进度条                   setProgressBarIndeterminateVisibility(false);                   //隐藏带进度的进度条                   setProgressBarVisibility(false);              }         });     }}

3.SeekBar--拖动改变图片的透明度

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context=".MainActivity" >     <ImageView        android:id="@+id/iv"        android:layout_width="match_parent"        android:layout_height="240dp"        android:src="@drawable/lijiang"        android:alpha="1"/>     <SeekBar        android:id="@+id/seekbar"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:max="255"        android:progress="255"        android:thumb="@drawable/ic_launcher"        />          <TextView        android:gravity="center_horizontal"        android:id="@+id/tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"/></LinearLayout>

 /** * SeekBar * 拖动SeekBar来改变图片的透明度     * @author 刘楠 * * 2016-2-19下午11:09:43 */public class MainActivity extends Activity {         private ImageView iv;         private SeekBar seekbar;         private TextView tv;          @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);                 iv = (ImageView) findViewById(R.id.iv);         seekbar = (SeekBar) findViewById(R.id.seekbar);         tv = (TextView) findViewById(R.id.tv);                         seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {                           @Override              public void onStopTrackingTouch(SeekBar seekBar) {                   tv.setText(seekBar.getProgress()+"");                                }                           @Override              public void onStartTrackingTouch(SeekBar seekBar) {                   tv.setText(seekBar.getProgress()+"");                                }                           @Override              public void onProgressChanged(SeekBar seekBar, int progress,                       boolean fromUser) {                   tv.setText(seekBar.getProgress()+"");                                     iv.setImageAlpha(progress);                                }         });     } }

4.RationBar---使用星星做为进度条,评价是常用

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context=".MainActivity" >     <ImageView        android:id="@+id/iv"        android:layout_width="match_parent"        android:layout_height="240dp"        android:src="@drawable/lijiang"        android:alpha="1"/>     <RatingBar        android:id="@+id/ratingbar"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:max="255"        android:progress="255"         android:numStars="5"         android:stepSize="0.5"/>          <TextView        android:gravity="center_horizontal"        android:id="@+id/tv"        android:layout_width="match_parent"        android:layout_height="wrap_content"/></LinearLayout>

/** * 使用星星做为进度条     * @author 刘楠 * * 2016-2-19下午11:14:00 */public class MainActivity extends Activity {     private ImageView iv;      private RatingBar ratingbar;      private TextView tv;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);         iv = (ImageView) findViewById(R.id.iv);         ratingbar = (RatingBar) findViewById(R.id.ratingbar);                 ratingbar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {                           @SuppressLint("NewApi")              @Override              public void onRatingChanged(RatingBar ratingBar, float rating,                       boolean fromUser) {                                     iv.setImageAlpha((int) (rating*255/5));                                }         });     } }

5.选项卡

8.TextSwitch
