Android View在没有XML的情况下对齐底部（以编程方式）

但使书种多，会有岁稔时。这篇文章主要讲述Android View在没有XML的情况下对齐底部（以编程方式）相关的知识，希望能为你提供帮助。
设置将视图以编程方式对齐到屏幕底部时出现问题。基本上我只想把我的admob广告放在屏幕底部。我不能用XML来做，因为它会更麻烦。现在我已经让广告正常工作，并将其手动添加到RelativeLayout，但默认情况下它出现在屏幕顶部。我试图使用重力命令，但无法使其工作。
这是代码片段：

_glSurfaceView = new CCGLSurfaceView(this); adView = new AdView(this, AdSize.BANNER, "a14e04559caea39"); adView.loadAd(new AdRequest()); adView.setGravity(Gravity.BOTTOM); RelativeLayout rl = new RelativeLayout(this); rl.addView(_glSurfaceView); rl.addView(adView); setContentView(rl); adView.loadAd(new AdRequest());

谁能帮我吗？
答案蜻蜓的回答对我有用。以下是参考的完整代码段

adView = new AdView(this, AdSize.BANNER, "xxxxxxxxxxxxxxx"); panel = new MySurfaceView(this); AdRequest adRequest = new AdRequest(); adRequest.addTestDevice(AdRequest.TEST_EMULATOR); RelativeLayout rl = new RelativeLayout(this); RelativeLayout.LayoutParams lay = new RelativeLayout.LayoutParams( RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); lay.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); rl.addView(panel); rl.addView(adView, lay); setContentView(rl); adView.loadAd(adRequest);

另一答案

RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); p.addRule(RelativeLayout.ALIGN_BOTTOM, tv.getId());

另一答案使用LayoutParams将广告添加到RelativeLayout，如下所示：

RelativeLayout.LayoutParams rparams = (LayoutParams) rl .getLayoutParams(); rparams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); ((ViewGroup) rl).addView(adView, rparams);

而不仅仅是

rl.addView(adView);

【Android View在没有XML的情况下对齐底部（以编程方式）】祝好运！ :)
另一答案

ImageButton buttonAdvance = new ImageButton(this); RelativeLayout.LayoutParams params = newRelativeLayout.LayoutParams(160, 160); params.leftMargin = 5; params.bottomMargin = 4; params.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM); buttonAdvance.setLayoutParams(params);
