Android 控制項seekbar進度條、ratingbar星星平分條

Android 控制項seekbar、ratingbar

1、Seekbar就是一個進度條；可拖動可改變；

拖動後：

原代碼如下：

布局檔案：

<?xml version="1.0"encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><SeekBar    android:id="@+id/seekbarld"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    /></LinearLayout>

JAVA代碼：

package lili.seekbar; import android.app.Activity;import android.os.Bundle;import android.widget.SeekBar;importandroid.widget.SeekBar.OnSeekBarChangeListener; public class SeekBarActivity extendsActivity {       /**Called when the activity is first created. */       privateSeekBar seekBar = null;             @Override       publicvoid onCreate(Bundle savedInstanceState) {              super.onCreate(savedInstanceState);              setContentView(R.layout.main);              //繫結控制項              seekBar= (SeekBar) findViewById(R.id.seekbarld);              //設定進度條條的最大值              seekBar.setMax(100);              //添加監聽器              seekBar.setOnSeekBarChangeListener(newSeekBarListener());                    }       //一個監聽器，該監聽器負責監聽進度條狀態 的改變       privateclass SeekBarListener implements OnSeekBarChangeListener {              //當進度條的進度發生 變化 時，會調用 該 方法              publicvoid onProgressChanged(SeekBar seekBar, int progress,                            booleanfromUser) {                     System.out.println(progress);              }              publicvoid onStartTrackingTouch(SeekBar seekBar) {                     System.out.println("start->"+ seekBar.getProgress());              }              publicvoid onStopTrackingTouch(SeekBar seekBar) {                     System.out.println("stop->"+ seekBar.getProgress());              }       }      }

2、Ratingbar是平分條；星星表示

點擊星星後：

原碼：

布局檔案：

<?xml version="1.0"encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><RatingBar    android:id="@+id/ratingbarld"    android:layout_height="wrap_content"    android:layout_width="wrap_content"    android:numStars="5"    android:stepSize="13.0" /></LinearLayout>

JAVA檔案：

package lili.ratingbar; import android.app.Activity;import android.os.Bundle;import android.widget.RatingBar; public class RatingBarActivity extends Activity{    /**Called when the activity is first created. */    privateRatingBar ratingBar=null;   @Override    publicvoid onCreate(Bundle savedInstanceState) {       super.onCreate(savedInstanceState);       setContentView(R.layout.main);        ratingBar=(RatingBar)findViewById(R.id.ratingbarld);       ratingBar.setOnRatingBarChangeListener(newRatingBarListener());    }   private class RatingBarListener implementsRatingBar.OnRatingBarChangeListener{        @Override       publicvoid onRatingChanged(RatingBar ratingBar, float rating,              booleanfromUser) {           System.out.println("rating-->"+rating);       }          }}

但是我們一般想把RatingBar裝飾的更好看，想把更好看的圖片用來替換系統預設的圖片,那麼應該怎麼改呢？
