对API 14和15使用{ "name": "myproject", "version": "0.0.1", "scripts": { "postinstall": "./node_modules/.bin/webdriver-manager update --standalone && ./node_modules/.bin/bower install", "test": "./node_modules/.bin/protractor test/functional/protractor.conf.js" }, "dependencies": { "async": "^0.9.0", "hapi": "~8.2.0", "hapi-seneca": "^1.0.3", "seneca": "git://github.com/rjrodger/seneca.git", "seneca-account": "^0.1.8", "seneca-auth": "git://github.com/rjrodger/seneca-auth.git", "seneca-card": "^0.1.3", "seneca-project": "^0.1.4", "seneca-user": "~0.2.10" }, "devDependencies": { "protractor": "~1.7.0", "bower": "~1.3.12" } } ，对API 16 +使用setBackgroundDrawable()：

所以你必须将Bitmap转换为BitmapDrawable

像

setBackground()

然后只需用下面的函数设置位图

 BitmapDrawable ob = new BitmapDrawable(getResources(), bitmap)
