1.通知Notification

通知就是在是上方的狀態欄彈出通知消息

 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    tools:context=".MainActivity" >

 

    <Button

        android:onClick="send"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

    <ImageView

        android:id="@+id/iv"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:src="@drawable/swift"/>

   

</LinearLayout>

</LinearLayout>

 

 

 

 

 

 

/**

public class MainActivity extends Activity {

 

     private Button btn1;

     private Button btn2;

3.SeekBar--拖動改變圖片的透明度

 

<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

 * 拖動SeekBar來改變圖片的透明度

 */

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---使用星星做為進度條,評價是常用

 

<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>

 

 

 

 

 

/**

 */

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.選項卡

public class MainActivity extends TabActivity

{

     @Override

     public void onCreate(Bundle savedInstanceState)

     {

         super.onCreate(savedInstanceState);

7.ViewFlipper

 

 

使用ViewFlipper來播放圖片 這個控件繼承了ViewAnimator

  調用showPrevious顯示上一張

  showNext();顯示下一張

     startFlipping();開始自動播放

     stopFlipping();停止播放

     設置進入的動畫效果與方向

     viewFlipper.setInAnimation(this, android.R.anim.slide_out_right);

     設置切換下一張時的動畫效果與方向

         viewFlipper.setOutAnimation(this, android.R.anim.slide_in_left);
