hello, how do I calculate the font size of a TextView so that always
occupy a certain percentage of the screen? now I spit it out:
-------8<---------------8<---------
.....
densityNormal = Float.parseFloat("1.0");
densitySub = Float.parseFloat("0.75");
densityIper = Float.parseFloat("1.5");
densityExtra = Float.parseFloat("2.0");
.....
textviewSample.setTextSize(getHeightPercentage(context,30));
.....
private float getHeightPercentage(Context context, int percentage) {
if (percentage > 0 && percentage < 100) {
float appHeight = context.getApplicationContext().getResources()
.getDisplayMetrics().heightPixels;
float appSPDensity = context.getApplicationContext().getResources()
.getDisplayMetrics().scaledDensity;
if (Float.compare(appSPDensity, densitySub) == 0) {
appHeight = appHeight + ((appHeight * 25) / 100);
//<---
} else if (Float.compare(appSPDensity, densityIper) == 0) {
appHeight = ((appHeight * 50) / 100) - appHeight;
//<---
} else if (Float.compare(appSPDensity, densityExtra) == 0) {
appHeight = ((appHeight * 200) / 100) - appHeight;
//<---
}
return new Float((appHeight * percentage) / 100);
} else
return -1;
}
-------8<---------------8<---------
but I can not integrate the different density of the screen,have you
any suggestions?8y3
