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
