我有2項活動。由於內容的原因,Android活動會產生黑屏
ActivityA從按鈕單擊開始activityB。
當按鈕被點擊時,我創建一個新的對話框,並顯示一個圖像作爲一種減少加載屏幕(不用進度條困擾)。
當activityB從ActivityA啓動對話框時被殺死,我立即在oncreate的頂部啓動一個新對話框。我爲活動B創造了很多東西。
創建一個adview,一些主視圖的文本並創建一個GLsurface渲染器。
問題是,當activityB的oncreate被調用時,我在兩個對話框之間出現了一個4秒的黑色屏幕。我想嘗試儘可能減少這種情況。
因此,無論如何都要讓活動B中的對話以自然的方式運行,而不是等待onCreate的其餘部分完成正在做的事情。將提供代碼,如果需要的話
更新。它是我的glsurface渲染器的創建,導致黑屏持續了很長時間。下面是活動B碼
public class ActivityB extends BaseGameActivity
{
/** Hold a reference to our GLSurfaceView */
private MyGLSurfaceView mGLSurfaceView;
public GamePlay GamePlay;
public GoogleApiClient mGoogleApiClient = null;
private AdView adView;
private static final String AD_UNIT_ID = "******************************";
private Button RotateButton;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
// load screen dialog
Dialog loader_dialog = new Dialog(this,android.R.style.Theme_Black_NoTitleBar_Fullscreen);
loader_dialog.setContentView(R.layout.loading_screen);
loader_dialog.show();
// Create an ad.
adView = new AdView(this);
adView.setAdSize(AdSize.SMART_BANNER);
adView.setAdUnitId(AD_UNIT_ID);
// Add the AdView to the view hierarchy. The view will have no size
// until the ad is loaded.
RelativeLayout layout = new RelativeLayout(this);
layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
// Create an ad request. Check logcat output for the hashed device ID to
// get test ads on a physical device.
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice("*****************************").build();
// Start loading the ad in the background.
adView.loadAd(adRequest);
final TextView Score = new TextView(this);
Score.setText(" 0");
RelativeLayout.LayoutParams scoreParams = new
RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
Score.setLayoutParams(scoreParams);
Typeface tf = Typeface.createFromAsset(getAssets(),"Fonts/test.ttf");
Score.setTextSize(getResources().getDimension(R.dimen.textsize));
Score.setTypeface(tf);
Score.setTextColor(Color.parseColor("#FDAA03"));
LayoutInflater inflater = (LayoutInflater) this.getSystemService(this.LAYOUT_INFLATER_SERVICE);
View userInterface = inflater.inflate(R.layout.user_interface, null);
GameButton = (Button) userInterface.findViewById(R.id.gamebutton);
GameButton.setOnTouchListener(new OnTouchListener()
{
@Override
public boolean onTouch(View v, MotionEvent event)
{
//irrelivant game stuff
}
});
// Check if the system supports OpenGL ES 2.0.
final ActivityManager activityManager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo configurationInfo = activityManager.getDeviceConfigurationInfo();
final boolean supportsEs2 = configurationInfo.reqGlEsVersion >= 0x20000;
if (supportsEs2)
{
// Request an OpenGL ES 2.0 compatible context.
mGLSurfaceView = new MyGLSurfaceView(this); new GLSurfaceView(this);
mGLSurfaceView.setEGLContextClientVersion(2);
final DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
// Set the renderer to our demo renderer, defined below.
mGoogleApiClient = getApiClient();
RelativeLayout.LayoutParams adParams =
new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT);
adParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
adParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
layout.addView(mGLSurfaceView);
layout.addView(userInterface);
layout.addView(Score);
layout.addView(adView, adParams);
mGLSurfaceView.setRenderer(new MyRenderer(this, Score, mGoogleApiClient),displayMetrics);
//Set main renderer
setContentView(layout);
}
else
{
// This is where you could create an OpenGL ES 1.x compatible
// renderer if you wanted to support both ES 1 and ES 2.
return;
}
}
@Override
protected void onResume()
{
// The activity must call the GL surface view's onResume() on activity onResume().
super.onResume();
mGLSurfaceView.onResume();
}
@Override
protected void onPause()
{
// The activity must call the GL surface view's onPause() on activity onPause().
super.onPause();
mGLSurfaceView.onPause();
}
}
將代碼顯示在'onCrate'頂部的對話框。如需更多幫助,請發佈一些代碼。 – Gumbo 2014-09-04 09:00:57
