我正在开发一个 android 应用程序，它现在是静态的。为了使其动态化，我正在考虑从网络服务器或谷歌驱动器获取图像。我随身携带的照片很少。如何从网络服务器或谷歌驱动器获取图像？这是我在下面给出的代码-

床.java

import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

public class Bed extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_bed);

    ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_bed, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == android.R.id.home) {
        this.finish();
        return true;
    } else {
        return super.onOptionsItemSelected(item);
    }

}
}

activity_bed.xml（目前，我已经给出了 5 个 ImageViews 和相应的 5 个图像，目前它是静态的。我想从 Web 服务器/谷歌驱动器获取这 5 个图像）。
