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(); } }
