Android--创建进度框ProgressDialog

1、布局文件progress_dialog_activity.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/btn_progress_dialog"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/btn_progress_dialog_text"
        android:layout_gravity="center_horizontal"/>
</LinearLayout>

2、Activity类ProgressDialogActivity.java

package cn.luxh.dialognew;

import android.app.Activity;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ProgressDialogActivity extends Activity {

    private Button btn_progress_dialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.progress_dialog_activity);
        handleBtnProgressDialogClick();
    }

    /**
     * 处理按钮事件
     */
    private void handleBtnProgressDialogClick() {
        btn_progress_dialog = (Button) findViewById(R.id.btn_progress_dialog);
        btn_progress_dialog.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                createProgressDialog();
            }
        });
    }

    /**
     * 生成进度对话框
     */
    private void createProgressDialog() {
        //显示进度对话框
        final ProgressDialog progressDialog = ProgressDialog.show(this, "提示", "处理中..."); 

        //业务处理
        new Thread(new Runnable(){
            @Override
            public void run() {
                try {
                    Thread.sleep(10000);
                    progressDialog.dismiss();//取消进度对话框
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }).start();
    }

}

　　一个带实时进度的对话框

代码如下：

package cn.luxh.dialognew;

import android.app.Activity;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class ProgressDialogActivity extends Activity {

    private Button btn_progress_dialog;

    private ProgressDialog progressDialog;

    private static final String TAG = "ProgressDialogActivity";

    //控制线程中断
    private static boolean isRun = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.progress_dialog_activity);
        handleBtnProgressDialogClick();
    }

    /**
     * 处理按钮事件
     */
    private void handleBtnProgressDialogClick() {
        btn_progress_dialog = (Button) findViewById(R.id.btn_progress_dialog);
        btn_progress_dialog.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                isRun = true;
                createProgressDialog2();
                progressDialog.show();
                progressDialog.setProgress(0);
                new Thread(new Runnable(){
                    @Override
                    public void run() {
                        int i = 1;
                        while(isRun && i<=20) {
                            try {
                                Log.d(TAG, "i is:"+i);
                                Thread.sleep(1500);
                                progressDialog.incrementProgressBy(100/20);
                                i++;
                            } catch (InterruptedException e) {
                                isRun = false;//中断线程
                                e.printStackTrace();
                            }
                        }
                    }
                }).start();
            }
        });
    }

    /**
     * 生成进度对话框
     */
    private void createProgressDialog2() {
        progressDialog = new ProgressDialog(this);
        progressDialog.setIcon(R.drawable.ic_launcher);
        progressDialog.setTitle("实时进度...");
        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        progressDialog.setCancelable(false);//设置模态窗口
        progressDialog.setButton(ProgressDialog.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                isRun = false;//中断线程
                Toast.makeText(getBaseContext(), "确定按钮被点击！", Toast.LENGTH_SHORT).show();
            }
        });
        progressDialog.setButton(ProgressDialog.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                isRun = false;//中断线程
                Toast.makeText(getBaseContext(), "取消按钮被点击！", Toast.LENGTH_SHORT).show();
            }
        });
