清单文件中添加的内容

<meta-data
android:name="design_width"
android:value="800"></meta-data>
<meta-data
android:name="design_height"
android:value="1280"></meta-data>

获取屏幕宽高

PackageManager pm = getPackageManager();
//获取宽高
try {
ActivityInfo info = pm.getActivityInfo(getComponentName(), PackageManager.GET_META_DATA);
int width = info.metaData.getInt("design_width-1");
int height = info.metaData.getInt("design_height-1");
Log.i(TAG, "onCreate: 高"+height);
Log.i(TAG, "onCreate: 宽"+width);
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}

AutoLayout框架使用以及dp pxsp单位换算

依赖

implementation 'com.zhy:autolayout:1.4.3'
