易采站长站为您分析Android 获得屏幕宽高的三种方式的相关资料,需要的朋友可以参考下
老风格，废话不多说了，直接给大家贴android获取屏幕宽高的代码了。
主要代码：
package com.km.screeninfo;
import android.os.Bundle;
import android.support.v.app.Fragment;
import android.support.v.app.FragmentActivity;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit();
}
}
/**
* A placeholder fragment containing a simple view.
