Dialog

1. 圆形旋转进度样式

public Dialog createSpinnerDialog(Context context, String msg) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.spinner_style_dialog, null);

    LinearLayout linearLayout = (LinearLayout) view.findViewById(R.id.ll_spinner_dialog);
    ImageView imageView = (ImageView) view.findViewById(R.id.iv_spinner);
    TextView textView = (TextView) view.findViewById(R.id.tv_spinner);

    Animation animation = AnimationUtils.loadAnimation(context, R.anim.loading_animation);
    imageView.startAnimation(animation);

    textView.setText(msg);

    Dialog dialog = new Dialog(context, R.style.loading_dialog);
    dialog.setCancelable(true);         // 设置按返回键时取消对话框
    dialog.setCanceledOnTouchOutside(false);    // 设置点击对话框外部时不取消对话框,默认为true
    dialog.setContentView(linearLayout, new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.MATCH_PARENT
    ));
    return dialog;
}

创建对话框并显示

createSpinnerDialog(this, "正在加载中...").show();

2. 帧动画进度样式

public Dialog createFrameDialog(Context context, String msg){
    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.frame_style_dialog, null);

    LinearLayout linearLayout = (LinearLayout) view.findViewById(R.id.ll_frame_dialog);
    ImageView imageView = (ImageView) view.findViewById(R.id.iv_frame);
    TextView textView = (TextView) view.findViewById(R.id.tv_frame);

    AnimationDrawable ad = (AnimationDrawable) imageView.getDrawable();
    ad.start();

    textView.setText(msg);

    Dialog dialog = new Dialog(context, R.style.loading_dialog);    //
    dialog.setCancelable(true);         // 设置按返回键时取消对话框
    dialog.setCanceledOnTouchOutside(false);    // 设置点击对话框外部时不取消对话框,默认为true
    dialog.setContentView(linearLayout, new LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            LinearLayout.LayoutParams.MATCH_PARENT
    ));

            Toast.makeText(MainActivity.this, R.string.text_alert_btn_positive_tip, Toast.LENGTH_SHORT).show();
        }
    });
    // 否定性质的按钮 (否,没有,取消)
    builder.setNegativeButton(R.string.text_alert_btn_negative, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(MainActivity.this, R.string.text_alert_btn_negative_tip, Toast.LENGTH_SHORT).show();
        }
    });
    // 中立性质的按钮 (不确定,沉默,保密,忽略,详细)
    builder.setNeutralButton(R.string.text_alert_btn_neutral, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(MainActivity.this, R.string.text_alert_btn_neutral_tip, Toast.LENGTH_SHORT).show();
        }
    });
    // 通过建造者来创建对话框
    AlertDialog dialog = builder.create();      // -
    // 显示对话框
    dialog.show();                              // -

    // 直接使用建造者显示对话框

        @Override
        public void onClick(DialogInterface dialog, int which, boolean isChecked) {
            if (isChecked) {
                results.add(languages[which]);

ProgressDialog

ProgressDialog基本使用说明

1. 创建ProgressDialog的两种方式

ProgressDialog dialog = new ProgressDialog(this);
dialog.show();
ProgressDialog dialog = ProgressDialog.show(this, null, "正在加载...");

静态方法show()的参数说明

public static ProgressDialog show(
    Context context,                // 上下文 
    CharSequence title,             // 标题
    CharSequence message,           // 消息内容
    boolean indeterminate,          // 不确定性,false为不确定性样式,true为确定性样式
    boolean cancelable,             // 是否可以取消
    OnCancelListener cancelListener // 取消事件监听器
);

2. 取消ProgressDialog对话框
Dialog.cancel()Dialog.dismiss()都可以删除对话框,但是使用cancel()方法会在删除对话框时回调DialogInterface.OnCancelListener监听器中的onCancel()方法,而dismiss()则不会进行回调。

3. 设置ProgressDialog进度条样式

dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);   // 设置水平进度条
dialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);      // 设置圆形旋转进度条

ProgressDialog使用示例

1. 圆形旋转进度条

private void createIndeterminateProgressDialog() {
    final ProgressDialog dialog = ProgressDialog.show(this, null, "正在加载...");
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Thread.sleep(3000);
                dialog.dismiss();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }).start();
}

2. 水平进度条

private void createDeterminateProgressDialog() {
    final ProgressDialog dialog = new ProgressDialog(this);
    dialog.setIcon(R.drawable.ic_action_download);  // 设置图标
    dialog.setTitle("当前下载进度");          // 设置标题
    dialog.setMessage("正在加载中...");      // 设置消息内容
    dialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);  // 设置水平进度条
    dialog.setMax(100);     // 设置最大进度值
    dialog.setCancelable(true);                 // 设置是否可以通过点击Back键取消
    dialog.setCanceledOnTouchOutside(false);    // 设置在点击Dialog外是否取消Dialog进度条
    dialog.setButton(DialogInterface.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(MainActivity.this, "确定", Toast.LENGTH_SHORT).show();
        }
    });
    dialog.setButton(DialogInterface.BUTTON_NEUTRAL, "忽略", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(MainActivity.this, "忽略", Toast.LENGTH_SHORT).show();
        }
    });
    dialog.setButton(DialogInterface.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();
        }
    });
    // 按Back键事件监听
    dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel(DialogInterface dialog) {
            Toast.makeText(MainActivity.this, "Cancel", Toast.LENGTH_SHORT).show();
        }
    });
    dialog.show();

    new Thread(new Runnable() {
        @Override
        public void run() {
            int i = 0;
            while (i < 100) {
                try {
                    i += 5;
                    Thread.sleep(200);              // 5000ms
                    dialog.incrementProgressBy(5);  // 更新进度
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            dialog.dismiss();
        }
    }).start();
}
