我正试图测试AlertDialog一下ActivityInstrumentationTestCase2.

这是原始代码:

    this.setmBtAppelerFixe(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            AlertDialog.Builder dialog = new AlertDialog.Builder(InterventionImmobiliereDetailsActivity.this);
            dialog.setTitle("Appel");
            dialog.setMessage("Appeler le contact ?");
            dialog.setCancelable(true);
            dialog.setNegativeButton("Non", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
            dialog.setPositiveButton("Oui", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    InterventionImmobiliereDetailsActivity.this.lancerIntentAppel(mIntervention.getTelContact());
                }
            });

            mAdAppelerFixe = dialog.create();
            mAdAppelerFixe.show();
        }
    });

现在我无法点击正面按钮.此代码似乎不起作用:

    mActivity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
            assertTrue(mLLAppelerFixe.performClick());

            AlertDialog mDialog = mActivity.getAdAppelerFixe();
            assertTrue(mDialog.isShowing());

            Button okButton = …
