在Android中获取屏幕宽度和高度

我如何获得屏幕的宽度和高度，并使用这个值在:

@Override protected void onMeasure(int widthSpecId, int heightSpecId) {
    Log.e(TAG, "onMeasure" + widthSpecId);
    setMeasuredDimension(SCREEN_WIDTH, SCREEN_HEIGHT - 
        game.findViewById(R.id.flag).getHeight());
}

当前回答

试试下面的代码:-

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

Display display = getWindowManager().getDefaultDisplay(); 
int width = display.getWidth();  // deprecated
int height = display.getHeight();  // deprecated

int width = getWindowManager().getDefaultDisplay().getWidth(); 
int height = getWindowManager().getDefaultDisplay().getHeight();

DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);

metrics.heightPixels;
metrics.widthPixels;

其他回答

只是通过parag和SpK更新答案，使其与当前SDK的向后兼容性保持一致:

int Measuredwidth = 0;  
int Measuredheight = 0;  
Point size = new Point();
WindowManager w = getWindowManager();

if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)    {
    w.getDefaultDisplay().getSize(size);
    Measuredwidth = size.x;
    Measuredheight = size.y; 
}else{
    Display d = w.getDefaultDisplay(); 
    Measuredwidth = d.getWidth(); 
    Measuredheight = d.getHeight(); 
}

DisplayMetrics dimension = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dimension);
        int width = dimension.widthPixels;
        int height = dimension.heightPixels;

我更新了Kotlin语言的答案!

对于Kotlin:您应该调用窗口管理器并获取指标。在那简单的方法之后。

val displayMetrics = DisplayMetrics()
windowManager.defaultDisplay.getMetrics(displayMetrics)

var width = displayMetrics.widthPixels
var height = displayMetrics.heightPixels

如何用Kotlin语言有效地独立活动地使用它?

这里，我在一般的Kotlin类中创建了一个方法。你可以在所有活动中使用它。

private val T_GET_SCREEN_WIDTH:String = "screen_width"
private val T_GET_SCREEN_HEIGHT:String = "screen_height"

private fun getDeviceSizes(activity:Activity, whichSize:String):Int{

    val displayMetrics = DisplayMetrics()
    activity.windowManager.defaultDisplay.getMetrics(displayMetrics)

    return when (whichSize){
        T_GET_SCREEN_WIDTH -> displayMetrics.widthPixels
        T_GET_SCREEN_HEIGHT -> displayMetrics.heightPixels
        else -> 0 // Error
    }
}

我使用下面的代码来获取屏幕尺寸

getWindow().getDecorView().getWidth()
getWindow().getDecorView().getHeight()

val displayMetrics = DisplayMetrics()
windowManager.defaultDisplay.getMetrics(displayMetrics)

var width = displayMetrics.widthPixels
var height = displayMetrics.heightPixels
