setGravity修改Toast弹出的位置

                    Toast toast = Toast.makeText(SearchActivity.this, "取消关注失败",
                            Toast.LENGTH_SHORT);
                    toast.setGravity(Gravity.CENTER, 0, 0);
                    toast.show();

这样设置会使Toast在中间弹出

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

  public void upperLeft(View v) {
    Toast toast = Toast.makeText(this, "Upper Left!",
        Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.TOP | Gravity.LEFT, 0, 0);
    toast.show();
  }

  public void upperRight(View v) {
    Toast toast = Toast.makeText(this, "Upper Right!",
        Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.TOP | Gravity.RIGHT, 0, 0);
    toast.show();
  }

  public void bottomLeft(View v) {
    Toast toast = Toast.makeText(this, "Bottom Left!",
        Toast.LENGTH_SHORT);

    toast.setGravity(Gravity.BOTTOM | Gravity.LEFT, 0, 0);
    toast.show();
  }

  public void bottomRight(View v) {
    Toast toast = Toast.makeText(this, "Bottom Right!",
        Toast.LENGTH_SHORT);
    toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT, 0, 0);
    toast.show();
  }

自己试一试吧，都是很简单能理解的东西
