获取屏幕宽度，将view移出屏幕再移动回来

public class MainActivity extends AppCompatActivity {
   private TextView kuandu;
    float curTranslationX;
    float width;
    float height;
    private Button out;
    private Button in;
　　 private View view;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        kuandu = (TextView) findViewById(R.id.kuandu);
        out = (Button) findViewById(R.id.out);
        in = (Button) findViewById(R.id.in);
        view =  findViewById(R.id.view);
        out.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                goOut();
            }
        });
        in.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                goIn();
            }
        });

        WindowManager manager = this.getWindowManager();
        DisplayMetrics outMetrics = new DisplayMetrics();
        manager.getDefaultDisplay().getMetrics(outMetrics);
        width = outMetrics.widthPixels;
        height = outMetrics.heightPixels;
        kuandu.setText("宽度是：" +width+ ",高度是" + height);

    }

    private void goOut() {
        curTranslationX = view.getTranslationX();
        ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationX", curTranslationX, width);
        animator.setDuration(1000);
        animator.start();

    }

    private void goIn() {
        curTranslationX = view.getTranslationX();
        ObjectAnimator animator = ObjectAnimator.ofFloat(view, "translationX", curTranslationX, 0);
        animator.setDuration(1000);
        animator.start();

    }

}
