如何設(shè)置 adSize 使其與所有設(shè)備上的父級(jí)寬度相匹配？我嘗試過(guò)setAdSize(AdSize.SMART_BANNER);，但由于某種原因，當(dāng)我使用它時(shí)，我的廣告沒(méi)有顯示。所以現(xiàn)在我使用mAdView.setAdSize(new AdSize(320,50);但不是在所有設(shè)備上寬度與全屏匹配。我的代碼        LinearLayout adContainer  = findViewById(R.id.adContainer);        mAdView = new NativeExpressAdView(getApplicationContext());        mAdView.setAdSize(new AdSize(320,50);        mAdView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");        adContainer.addView(mAdView);        LinearLayout adContainer2  = findViewById(R.id.adContainer2);        mAdView2 = new NativeExpressAdView(getApplicationContext());        mAdView2.setAdSize(new AdSize(320,50);        mAdView2.setAdUnitId("ca-app-pub-3940256099942544/6300978111");        adContainer2.addView(mAdView2);        AdRequest adRequest = new AdRequest.Builder().addTestDevice("4EF772AE9549741BE0E1FCA236C7382C").build();        mAdView.loadAd(adRequest);        mAdView2.loadAd(adRequest);編輯我試過(guò)mAdView.setAdSize(new AdSize(AdSize.FULL_WIDTH, AdSize.AUTO_HEIGHT));顯示的是320*100的廣告，但是左右兩邊有黑色區(qū)域，請(qǐng)問(wèn)如何設(shè)置廣告尺寸才能滿屏？
