核心代码:
@Override
public void onClick(View view) {
switch (view.getId()) {
//动画进度条
case R.id.anim:
//显示动画进度条
showRoundProcessDialog(this, R.layout.loading_process_dialog_anim);
break;
//颜色进度条
case R.id.color:
//显示颜色进度条
showRoundProcessDialog(this, R.layout.loading_process_dialog_color);
break;
//图片进度条
case R.id.icon:
//显示图片进度条
showRoundProcessDialog(this, R.layout.loading_process_dialog_icon);
break;
default:
break;
}
}
public void showRoundProcessDialog(Context mContext, int layout) {
//初始化进度条
mDialog = new AlertDialog.Builder(mContext).create();
//显示进度条
mDialog.show();
// 注意此处要放在show之后 否则会报异常
mDialog.setContentView(layout);
// mDialog.setCancelable(false); //false设置点击其他地方不能取消进度条
}
