我用四个按钮（上，下，左，右）和另外我有形象。我必须相应地移动图像时，我preSS UP按钮，我应该将图像向上的方向，当我preSS同样留下剩余的两个方向，应该将图像中左侧direction.I都的onclick侦听器，然后我用我试图利用移动X光图像，Y坐标ordinates.I怎么不拍X，Y坐标。
下面是code。
公共类MainActivity扩展活动实现OnClickListener {
按键向上，左，右，下，
ImageView的I1;
保护无效的onCreate（包savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_main）;
高达=（按钮）findViewById（R.id.button1）;
左=（按钮）findViewById（R.id.button2）;
右=（按钮）findViewById（R.id.button3）;
下来=（按钮）findViewById（R.id.button4）;
I1 =（ImageView的）findViewById（R.id.imageView1）;
up.setOnClickListener（本）;
}
公共无效的onClick（查看为arg0）{
Toast.makeText（getApplication（），UP，5000）.show（）;
RelativeLayout.LayoutParams mParams =（RelativeLayout.LayoutParams）
i1.getLayoutParams（）;
INT X =（int）的getRawx（）;
INT Y =（INT）getRawY（）;
mParams.leftMargin = X-50;
mParams.topMargin = Y-50;
i1.setLayoutParams（mParams）;
}
}
您好， 我已经更新了以下code，请检查一下。

解决方案
我认为这个问题是（INT）getRawx（）; 和（ INT）getRawy（）; ，你正在呼吁这个活动的方法和我不太确定你真的需要这些值
您可以尝试：
mParams.leftMargin + = 50;
或
INT X = mParams.leftMargin;
mParams.leftMargin = X + 50
I used four buttons (Up,down,Left,Right) and also i have image. I have to move the image accordingly when i press UP button i should move image in upward direction and when i press left similarly remaining both direction it should move image in left direction.I have used onclick listener and then i am trying to move image using X,Y co-ordinates.I don't how take X,Y co-ordinates.
Here is the code.
public class MainActivity extends Activity implements OnClickListener {
Button up,left,right,down;
ImageView i1;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
up=(Button)findViewById(R.id.button1);
left=(Button)findViewById(R.id.button2);
right=(Button)findViewById(R.id.button3);
down=(Button)findViewById(R.id.button4);
i1=(ImageView)findViewById(R.id.imageView1);
up.setOnClickListener(this);
}
public void onClick(View arg0) {
Toast.makeText(getApplication(),"UP",5000).show();
RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams)
i1.getLayoutParams();
int x = (int)getRawx();
int y = (int)getRawY();
mParams.leftMargin = x-50;
mParams.topMargin = y-50;
i1.setLayoutParams(mParams);
}
}
HI, I have updated code below please check it.
package com.example.motion;
public class MainActivity extends Activity implements OnClickListener {
Button up,left,right,down;
ImageView i1;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
up=(Button)findViewById(R.id.button1);
left=(Button)findViewById(R.id.button2);
right=(Button)findViewById(R.id.button3);
down=(Button)findViewById(R.id.button4);
i1=(ImageView)findViewById(R.id.imageView1);
up.setOnClickListener(this);
down.setOnClickListener(this);
left.setOnClickListener(this);
right.setOnClickListener(this);
}
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId())
{
case R.id.button1:
{
Toast.makeText(getApplication(),"UP",Toast.LENGTH_SHORT).show();
RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams)
i1.getLayoutParams();
mParams.topMargin -= 20;
i1.setLayoutParams(mParams);
break;
}
case R.id.button4:
{
Toast.makeText(getApplication(),"DOWN",Toast.LENGTH_SHORT).show();
RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams)
i1.getLayoutParams();
mParams.topMargin += 20;
i1.setLayoutParams(mParams);
break;
}
case R.id.button2:
{
Toast.makeText(getApplication(),"LEFT",Toast.LENGTH_SHORT).show();
RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams)
i1.getLayoutParams();
mParams.leftMargin -= 20;
i1.setLayoutParams(mParams);
break;
}
case R.id.button3:
{
Toast.makeText(getApplication(),"RIGHT",Toast.LENGTH_SHORT).show();
RelativeLayout.LayoutParams mParams = (RelativeLayout.LayoutParams)
i1.getLayoutParams();
mParams.leftMargin += 20;
i1.setLayoutParams(mParams);
break;
}
}
}
}
解决方案
I think the problem is (int)getRawx(); and (int)getRawy();, you are calling this methods on Activity and I'm not so sure you really need those values.
you could try:
mParams.leftMargin += 50;
or
int x = mParams.leftMargin;
mParams.leftMargin = x + 50
