Android控件之ProgressBar

1,带有进度条的ProgressBar

 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

     // Request the progress bar to be shown in the title
     requestWindowFeature(Window.FEATURE_PROGRESS);
     setContentView(R.layout.progressbar_1);
     setProgressBarVisibility(true);//设置在title里的ProgressBar可见

     final ProgressBar progressHorizontal = (ProgressBar) findViewById(R.id.progress_horizontal);

     setProgress(progressHorizontal.getProgress() * 100);//为title中的ProgressBar设置进度
     setSecondaryProgress(progressHorizontal.getSecondaryProgress() * 100);//为title中的ProgressBar设置二级进度

     Button button = (Button) findViewById(R.id.increase);//一级进度递增
     button.setOnClickListener(new Button.OnClickListener() {
         public void onClick(View v) {
             progressHorizontal.incrementProgressBy(1);
             // Title progress is in range 0..10000
             setProgress(100 * progressHorizontal.getProgress());//为title中的ProgressBar设置进度
         }
     });

     button = (Button) findViewById(R.id.decrease);//一级进度递减
     button.setOnClickListener(new Button.OnClickListener() {
         public void onClick(View v) {
             progressHorizontal.incrementProgressBy(-1);
             // Title progress is in range 0..10000
             setProgress(100 * progressHorizontal.getProgress());//为title中的ProgressBar设置进度
         }
     });

     button = (Button) findViewById(R.id.increase_secondary);//二级进度递增
     button.setOnClickListener(new Button.OnClickListener() {
         public void onClick(View v) {
             progressHorizontal.incrementSecondaryProgressBy(1);
             // Title progress is in range 0..10000
             setSecondaryProgress(100 * progressHorizontal.getSecondaryProgress());
         }
     });

     button = (Button) findViewById(R.id.decrease_secondary);//二级进度递减
     button.setOnClickListener(new Button.OnClickListener() {
         public void onClick(View v) {
             progressHorizontal.incrementSecondaryProgressBy(-1);
             // Title progress is in range 0..10000
             setSecondaryProgress(100 * progressHorizontal.getSecondaryProgress());
         }
     });

 }

配置文件 :

 <ProgressBar android:id="@+id/progress_horizontal"
     style="?android:attr/progressBarStyleHorizontal"
     android:layout_width="200dip"
     android:layout_height="wrap_content"
     android:max="100"
     android:progress="50"
     android:secondaryProgress="75" />

2, 转圈的样式的ProgressBar

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:orientation="vertical" >

     <ProgressBar
         android:id="@+android:id/progress_large"
         style="?android:attr/progressBarStyleLarge"//大样式
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" />

     <ProgressBar                                  //默认
         android:id="@+android:id/progress"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" />

     <ProgressBar
         android:id="@+android:id/progress_small"   //小样式
         style="?android:attr/progressBarStyleSmall"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" />

     <ProgressBar                                   //小标题样式
         android:id="@+android:id/progress_small_title"
         style="?android:attr/progressBarStyleSmallTitle"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" />

 </LinearLayout>

Java代码:

 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

     // Request for the progress bar to be shown in the title
     requestWindowFeature(Window.FEATURE_<span style="color:#ff0000;">INDETERMINATE</span>_PROGRESS);

     setContentView(R.layout.progressbar_2);

     // Make sure the progress bar is visible
     setProgressBarVisibility(true);
 }

效果:

3,Dialog样式的ProgressBar

 private static final int DIALOG1_KEY = 0;
    private static final int DIALOG2_KEY = 1;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.progressbar_3);

        Button button = (Button) findViewById(R.id.showIndeterminate);
        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                showDialog(DIALOG1_KEY);
            }
        });

        button = (Button) findViewById(R.id.showIndeterminateNoTitle);
        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                showDialog(DIALOG2_KEY);
            }
        });
    }

    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
            case DIALOG1_KEY: {
                ProgressDialog dialog = new ProgressDialog(this);
                dialog.setTitle("Indeterminate");
                dialog.setMessage("Please wait while loading...");
                dialog.set<span style="color:#ff0000;">Indeterminate</span>(true);//设置转圈的效果
                dialog.setCancelable(true);
                return dialog;
            }
            case DIALOG2_KEY: {
                ProgressDialog dialog = new ProgressDialog(this);
                dialog.setMessage("Please wait while loading...");
                dialog.set<span style="color:#ff0000;">Indeterminate</span>(true);//设置转圈的效果
                dialog.setCancelable(true);
                return dialog;
            }
        }
        return null;
    }

效果:

4,在title上面的转圈的ProgressBar

 private boolean mToggleIndeterminate = false;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);

     // Request progress bar
     requestWindowFeature(Window.FEATURE_<span style="color:#ff0000;">INDETERMINATE</span>_PROGRESS);//转圈样的ProgressBar
     setContentView(R.layout.progressbar_4);
     setProgressBarIndeterminateVisibility(mToggleIndeterminate);//是否可见

     Button button = (Button) findViewById(R.id.toggle);
     button.setOnClickListener(new Button.OnClickListener() {
         public void onClick(View v) {
             mToggleIndeterminate = !mToggleIndeterminate;//如果是false,设成true,如果是true设成false.
             setProgressBarIndeterminateVisibility(mToggleIndeterminate);//是否可见
         }
     });
 }
