Android进度条控件ProgressBar使用

ProgressBar有四种样式，圆形的（大，中，小）和直条形的（水平）

对应的style为

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <ProgressBar        android:id="@+id/progressBar1"        style="?android:attr/progressBarStyleLarge"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <ProgressBar        android:id="@+id/progressBar2"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <ProgressBar        android:id="@+id/progressBar3"        style="?android:attr/progressBarStyleSmall"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <ProgressBar        android:id="@+id/progressBar4"        style="?android:attr/progressBarStyleHorizontal"        android:layout_width="match_parent"        android:layout_height="wrap_content" /></LinearLayout>

注：style不写默认为中型进度条

使用requestWindowFeature来实现带进度条的标题栏

import android.support.v7.app.ActionBarActivity;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.Window;public class MainActivity extends ActionBarActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //启用精确显示进度的进度条和不显示精度的进度条标题栏        requestWindowFeature(Window.FEATURE_PROGRESS);        requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);        setContentView(R.layout.activity_main);                //设置可见性        setProgressBarVisibility(true);        setProgressBarIndeterminateVisibility(true);        //设置精确进度条的值，默认10000上限，达到10000后进度条不显示        setProgress(9999);    }}

在activity中对ProgressBar进行简单操作

用TextView实时显示第一进度条和第二进度条

import android.support.v7.app.ActionBarActivity;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.view.View.OnClickListener;import android.view.Window;import android.widget.Button;import android.widget.ProgressBar;import android.widget.TextView;public class MainActivity extends ActionBarActivity implements OnClickListener{    private ProgressBar progress;    private Button add, reduce, reset;    private TextView text;        @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //设置无标题栏        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.activity_main);        //初始化        init();    }        private void init() {        progress = (ProgressBar) findViewById(R.id.horiz);        add = (Button) findViewById(R.id.add);        reduce  = (Button) findViewById(R.id.reduce);        reset  = (Button) findViewById(R.id.reset);        text =  (TextView) findViewById(R.id.textView1);                //获取第一进度条进度        int first = progress.getProgress();        //获取第二进度条进度        int second = progress.getSecondaryProgress();        //获取最大进度        int max = progress.getMax();        text.setText(                "第一进度百分比:"+(int)(first/(float)max*100)+                "% 第二进度百分比:"+(int)(second/(float)max*100)+"%");        add.setOnClickListener(this);        reduce.setOnClickListener(this);        reset.setOnClickListener(this);    }    @Override    public void onClick(View v) {        switch (v.getId()) {        case R.id.add:            //增加第一进度条和第二进度条            progress.incrementProgressBy(10);            progress.incrementSecondaryProgressBy(10);            break;        case R.id.reduce:            progress.incrementProgressBy(-10);            progress.incrementSecondaryProgressBy(-10);            break;        case R.id.reset:            progress.setProgress(50);            progress.setSecondaryProgress(80);            break;        }        text.setText(                "第一进度百分比:"+(int)(progress.getProgress()/(float)progress.getMax()*100)+                "% 第二进度百分比:"+(int)(progress.getSecondaryProgress()/(float)progress.getMax()*100)+"%");    }    }

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <ProgressBar        android:id="@+id/progressBar1"        style="?android:attr/progressBarStyleLarge"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <ProgressBar        android:id="@+id/progressBar2"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <ProgressBar        android:id="@+id/progressBar3"        style="?android:attr/progressBarStyleSmall"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <ProgressBar        android:id="@+id/horiz"        android:max="100"        android:secondaryProgress="80"        android:progress="50"        style="?android:attr/progressBarStyleHorizontal"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <Button        android:id="@+id/add"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/bt1" />    <Button        android:id="@+id/reduce"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/bt2" />    <Button        android:id="@+id/reset"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/bt3" />    <TextView        android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="TextView" /></LinearLayout>

使用Dialog形式

import android.support.v7.app.ActionBarActivity;import android.app.Dialog;import android.app.ProgressDialog;import android.content.DialogInterface;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.view.View.OnClickListener;import android.view.Window;import android.widget.Button;import android.widget.ProgressBar;import android.widget.TextView;import android.widget.Toast;public class MainActivity extends ActionBarActivity{    private ProgressDialog progress;        @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        //设置无标题栏        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.activity_main);                init();    }        private void init() {        //设置ProgressDialog的显示                        //新建对象                progress = new ProgressDialog(this);                //设置风格                progress.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);                //设置标题                progress.setTitle("reading");                //设置文本内容                progress.setMessage("please waiting");                //设置图标                progress.setIcon(R.drawable.ic_launcher);                                progress.setMax(100);                progress.incrementProgressBy(50);                //是否非精确显示                progress.setIndeterminate(false);                progress.setButton(DialogInterface.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {                    @Override                    public void onClick(DialogInterface dialog, int which) {                        //此处不能写this                        Toast.makeText(MainActivity.this, "ok...", Toast.LENGTH_SHORT).show();                    }                });                //是否可以点击取消键(android自带的返回键)                progress.setCancelable(false);                //显示                progress.show();    }    }
