在下面的代码中，我希望在用户单击“检查根目录”后有一个旋转样式的进程对话框 5 秒钟。基本上，用户点击按钮后，进程对话框会显示“请稍候...”5 秒钟，然后显示结果。 我怎么做 ？请帮忙!
Button Root = (Button) findViewById(R.id.Root);
Root.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
if (RootTools.isAccessGiven()) {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("Congratulations!");
builder.setMessage("You Have Root Access!");
builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
else {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("Oops!");
builder.setMessage("No Root Access!");
builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
}
最佳答案
private Handler mTimerHandler = new Handler();
private ProgressDialog mProgressDialog = null;
private Button Root;
@Override
protected void onCreate(Bundle savedInstanceState) {
...........
Root = (Button) findViewById(R.id.Root);
Root.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
mProgressDialog = ProgressDialog.show(MainActivity.this, "", "Please wait...", true);
mTimerHandler.postDelayed(mTimerExecutor, 5000);
}
});
...........
}
private Runnable mTimerExecutor = new Runnable() {
@Override
public void run() {
if (mProgressDialog != null) {
mProgressDialog.dismiss();
}
showDialog();
}
};
private void showDialog() {
if (RootTools.isAccessGiven()) {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("Congratulations!");
builder.setMessage("You Have Root Access!");
builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setIcon(R.drawable.ic_launcher);
builder.setTitle("Oops!");
builder.setMessage("No Root Access!");
builder.setPositiveButton("OKAY", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
}
