我的进度条有java问题安卓 studio没有进展
我试着填充一个叫做“金属件”的表格，我使用了一个确定的进度条，这样它在填充表格的过程中会继续前进。但问题是我的进度对话框没有进展。这是我的密码：
metalPieces.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
MyApplication myApp = ((MyApplication)getApplicationContext());
if(!myApp.getMetalPiecesTablePopulated()) {
myApp.setMetalPiecesTablePopulated(true);
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setMax(653);
progressDialog.setMessage("Loading....");
progressDialog.setTitle("Populating metal pieces table");
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.show();
Thread thread = new Thread() {
@Override
public void run() {
try {
Integer incrementValue = 1;
Looper.prepare();
MyHandler handle = new MyHandler();
Looper.loop();
MetalPiece metalPiece;
AssetManager am = getAssets();
InputStream is = null;
try {
is = am.open("catalogue.xlsx");
} catch (IOException e) {
e.printStackTrace();
}
Workbook wb = null;
try {
wb = Workbook.getWorkbook(is);
} catch (IOException e) {
e.printStackTrace();
}
Sheet sheet = wb.getSheet(0);
for(int row = 1 ; row <= 653; row++){
String typeProfile = sheet.getCell(0, row).toString();
String poids = sheet.getCell(1, row).toString();
metalPiece = new MetalPiece();
metalPiece.setType(typeProfile);
metalPiece.setFamily("Profile");
metalPiece.setPoids(Float.parseFloat(poids));
metalPiece.setUnit("Mètre");
adapter.saveMetalPiece(metalPiece);
handle.sendEmptyMessage(incrementValue);
}
progressDialog.dismiss();
intent = new Intent(MainActivity.this, MetalPieces.class);
MainActivity.this.startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
};
thread.start();
}
else {
intent = new Intent(MainActivity.this, MetalPieces.class);
MainActivity.this.startActivity(intent);
}
}
});
我也在使用这个类：
class MyHandler extends Handler {
@Override
public void handleMessage(@NonNull Message msg){
super.handleMessage(msg);
progressDialog.incrementProgressBy(msg.what);
}
}
当我点击按钮进入金属件列表时，出现以下错误：

你能告诉我，我填这张桌子的时候做错了什么吗
