ProgressBar、ProgessDialog-用法(详解)

style="@android:style/Widget.Holo.Light.ProgressBar"style="@android:style/Widget.DeviceDefault.Light.ProgressBar.Large"...

style="@android:style/Widget.ProgressBar.Horizontal"style="@android:style/Widget.DeviceDefault.Light.ProgressBar.Horizontal"...

requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);setProgressBarIndeterminateVisibility(true);

requestWindowFeature(Window.FEATURE_PROGRESS);setProgressBarVisibility(true);

<!--最大显示进度-->android:max<!--第一显示进度-->android:progress<!--第二显示进度-->android:secondaryProgress<!--置是否精确显示；true为不精确，false为精确-->android:indeterminate<!--加载自定义样式-->android:progressDrawable

public class ProgessBarActivity extends Activity implements View.OnClickListener{  private ProgressBar progressBar;  private TextView text;  private Button addFirst;  private Button addSecond;  private Button subFirst;  private Button subSecond;  private Button reset;  private int first;  private int second;  private int max;  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_progess_bar);    init();  }  private void init() {    progressBar = (ProgressBar) findViewById(R.id.progress_bar);    text = (TextView) findViewById(R.id.text);    addFirst = (Button) findViewById(R.id.add_first);    subFirst = (Button) findViewById(R.id.sub_first);    addSecond = (Button) findViewById(R.id.add_second);    subSecond = (Button) findViewById(R.id.sub_second);    reset = (Button) findViewById(R.id.reset);    //获取第一、第二、最大进度    first = progressBar.getProgress();    second = progressBar.getSecondaryProgress();    max = progressBar.getMax();    addFirst.setOnClickListener(this);    addSecond.setOnClickListener(this);    subFirst.setOnClickListener(this);    subSecond.setOnClickListener(this);    reset.setOnClickListener(this);  }  @Override  public void onClick(View v) {    switch (v.getId()) {      case R.id.add_first:        //第一进度加10        progressBar.incrementProgressBy(10);        break;      case R.id.add_second:        //第二进度加10        progressBar.incrementSecondaryProgressBy(10);        break;      case R.id.sub_first:        progressBar.incrementProgressBy(-10);        break;      case R.id.sub_second:        progressBar.incrementSecondaryProgressBy(-10);        break;      case R.id.reset:        //重置为初始数值        progressBar.setProgress(30);        progressBar.setSecondaryProgress(60);        break;    }    //更新文本内容    text.setText("第一进度为" + (int) (1.0*first/max*100) + "%，第二进度为" + (int) (1.0*second/max*100) + "%");  }}

ProgressDialog(Context context)ProgressDialog(Context context, int theme)//theme为对话框样式

//设置进度条样式setProgressStyle(int style)//设置对话框标题setTitle(String title)//设置对话框本文信息setMessage(CharSequence message)//设置对话框图标setIcon(Drawable d)//设置按钮，whichButton为按钮类型，text为按钮名称，listener为监听器setButton(int whichButton, CharSequence text, OnClickListener listener)//显示对话框show()

public class ProgressDialogActivity extends Activity {  private ProgressDialog proDialog;  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_progress_dialog);    findViewById(R.id.show).setOnClickListener(new View.OnClickListener() {      @Override      public void onClick(View v) {        //新建对话框        proDialog = new ProgressDialog(ProgressDialogActivity.this);        //设置进度条样式        proDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);        //设置对话框标题        proDialog.setTitle("初识ProgressDialog");        //设置提示对话框文本        proDialog.setMessage("好好学习，天天向上！");        //设置对话框显示图标        proDialog.setIcon(R.drawable.ic_launcher);        //设置进度条最大进度，默认为10000        proDialog.setMax(100);        //设置初始第一进度        proDialog.incrementProgressBy(30);        //设定取消按钮        proDialog.setButton(DialogInterface.BUTTON_POSITIVE, "取消", new DialogInterface.OnClickListener() {          @Override          public void onClick(DialogInterface dialog, int which) {            dialog.cancel();          }        });        //显示对话框        proDialog.show();      }    });  }}
