自定义进度条:

/**
 * 自定义进度条类
 *
 * @author guilin
 * @date 16/5/13
 */
public class CProgressDialog extends Dialog {

    TextView tvProgressText;

    public CProgressDialog(Context context) {
        this(context, true);
    }

    public CProgressDialog(Context context, boolean cancelable) {
        super(context, R.style.DefaultProgressDialog);
        this.setCancelable(cancelable);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog_progress);
        tvProgressText = (TextView) findViewById(R.id.tv_progress_text);
    }

    public void setProgressText(String text) {
        tvProgressText.setText(text);
    }
}

 封装:

protected CProgressDialog loadingDialog;

protected void showLoadingDialog() {
    showLoadingDialog(true, "加载中...");
}

/**
 * 显示进度Dialog
 */
protected void showLoadingDialog(boolean cancelable, String progressText) {
    if (loadingDialog == null) {
        loadingDialog = new CProgressDialog(this, cancelable);
    }
    loadingDialog.setCancelable(cancelable);
    loadingDialog.show();
    loadingDialog.setProgressText(progressText);
}

protected void showLoadingDialog(String progressText) {
    showLoadingDialog(true, progressText);
}

/**
 * 取消进度Dialog
 */
protected void dismissLoadingDialog() {
    if (loadingDialog != null &&
            loadingDialog.isShowing()) {
        loadingDialog.dismiss();
    }
}

调用:

protected void showLoadingDialog() {
    if (mActivity == null) {
        ((BaseActivity) getActivity()).showLoadingDialog();
    } else {
        ((BaseActivity) mActivity).showLoadingDialog();
    }
}
