Android 什么是0，0声明，在"；。设置边距（imgX，imgY，0，0）“？我能正确理解X，Y坐标吗？

我目前正在尝试将ImageButton移动到Android应用程序中的某个X和Y位置。（Api级别15到22）并且图像的大小不保持不变。这是扭曲的。我首先假设是在以下代码中声明0，0：

marginParams.setMargins(imgX, imgY, 0, 0);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
img.setLayoutParams(layoutParams);

所以我试着包装内容。但它什么也没做

marginParams.setMargins(imgX, imgY, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
img.setLayoutParams(layoutParams);

以下是所有代码（如果需要）：

public class MainActivity extends ActionBarActivity {

    public EditText collectedTextEdit;
    public ImageButton candyEdit;
    public int collected = 0;
    public int screenWidth = 300;
    public int screenHeight = 300;
    public final int candySize = 50;
    Random random = new Random();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        collectedTextEdit = (EditText) findViewById(R.id.collectedText);
        candyEdit = (ImageButton) findViewById(R.id.candy);
        collectedTextEdit.setText("Collected: " + collected);

        Display display = getWindowManager().getDefaultDisplay();
        Point size = new Point();
        display.getSize(size);
        screenWidth = size.x;
        screenHeight = size.y;

        addListenerOnButton();
    }

    public void addListenerOnButton() {
        candyEdit.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                collected += 1;
                collectedTextEdit.setText("Collected: " + collected);

                int candyX = random.nextInt(screenWidth);
                int candyY = random.nextInt(screenHeight);
                System.out.println(candyX + " : " + candyY);

                //RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
                MarginLayoutParams marginParams = new MarginLayoutParams(candyEdit.getLayoutParams());
                marginParams.setMargins(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, candyX, candyY);
                RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(marginParams);
                //layoutParams.WRAP_CONTENT;
                candyEdit.setLayoutParams(layoutParams);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

下面是ImageButton的声明：

<ImageButton
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/candy"
        android:background="@drawable/candy"
        android:contentDescription="@string/candyImg"
        android:clickable="true"
        android:layout_below="@+id/collectedText"
        android:layout_alignRight="@+id/collectedText"
        android:layout_alignEnd="@+id/collectedText" />

请帮帮我！如果您需要任何其他代码示例，请随时询问，我会马上开始

你能用imagebutton显示你的代码是什么样子吗？当然，现在就添加它！：）出于好奇，您是否尝试过在xml中使高度/宽度保持静态？e、 g.30dp是的，我会在申报时出示
