先是布局页面

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:scrollbars="vertical"     android:orientation="vertical" >    <Button         android:id="@+id/myButton1"    android:layout_width="fill_parent"    android:layout_height="wrap_content"        />            <TextView         android:id="@+id/myTextView1"    android:layout_width="fill_parent"    android:layout_height="wrap_content"                      />    </LinearLayout>

再是主 activity

package sql.com;import android.app.Activity;import android.app.ProgressDialog;import android.os.Bundle;import android.view.View;import android.widget.Button;import android.widget.TextView; public class SqlActivity extends Activity{  private Button mButton1;  private TextView mTextView1;  public ProgressDialog myDialog = null;    /** Called when the activity is first created. */  @Override  public void onCreate(Bundle savedInstanceState)  {    super.onCreate(savedInstanceState);    setContentView(R.layout.main);        mButton1 =(Button) findViewById(R.id.myButton1);    mTextView1 = (TextView) findViewById(R.id.myTextView1);    mButton1.setOnClickListener(myShowProgressBar);  }    Button.OnClickListener myShowProgressBar = new Button.OnClickListener()  {    public void onClick(View arg0)    {      final CharSequence strDialogTitle = "请稍等";      final CharSequence strDialogBody = "数据读取中 . . . .";            // 显示Progress对话框      myDialog = ProgressDialog.show                 (                   SqlActivity.this,                   strDialogTitle,                   strDialogBody,                    true                 );            mTextView1.setText(strDialogBody);            new Thread()      {         public void run()        {           try          {             /*在这里写上要后台运行的代码段 */            /* 为了明显看见效果，以暂停3秒作为示范*/            sleep(3000);          }          catch (Exception e)          {            e.printStackTrace();          }          finally          {            // 卸载所创建的myDialog对象            myDialog.dismiss();          }        }      }.start(); /* 开始运行线程 */    } /*End: public void onClick(View arg0)*/  };}

自定义字体颜色

1, 现在在 res/values/styles.xml 写入

<?xml version="1.0" encoding="UTF-8"?><resources><style name="myDialog" parent="@android:style/Theme.Dialog">    <item name="android:windowBackground">@android:color/transparent</item>    <item name="android:textColor">#ff0000</item></style> </resources>

然后在 T3Activity.java 中

public class T3Activity extends Activity {    /** Called when the activity is first created. */ProgressDialog myDialog;     @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        // 每次使用需要调用如下， 进行 new 一下 ， ----        myDialog = new ProgressDialog(T3Activity.this, R.style.myDialog);//加载style                myDialog.setMessage("sss");        myDialog.show();// =============================================//OK 之后只需 dismiss();myDialog.dismiss();      }      }
