為什么我的自定義ImageView的onClickListener沒有注冊？

Question

我有一個平移縮放相對布局，在其中我添加了25個代表星圖上系統的圖像視圖。 這占據了屏幕的2/3。 另外1/3顯示有關單擊任何相應系統圖像視圖的信息。 但是，我的onClickListener方法沒有觸發。 我使用了調試模式，在onClick方法的開頭附近有一個斷點，以確保它沒有觸發，而不僅僅是顯示不正確。 這是相關的代碼。

public class StarMapActivity extends AppCompatActivity implements View.OnClickListener {
InteractiveView starMap;
TextView systemNameView;
TextView systemFactionView;
TextView systemCoordinatesView;
TextView systemPlanetsNumberView;
 protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_star_map);

    starMap = (InteractiveView) findViewById(R.id.myStarMapInteractiveView);
    systemNameView = (TextView) findViewById(R.id.systemNameView);
    systemFactionView = (TextView) findViewById(R.id.systemFactionView);
    systemCoordinatesView = (TextView) findViewById(R.id.systemCoordinatesView);
    systemPlanetsNumberView = (TextView) findViewById(R.id.systemPlanetsNumberView);

 for (int i = 0; i < 25; i++) {          plotSystem(PlayerCharacterInfo.currentPlayerCharacter.occupiedSector.starSystems[i], i);
    }
}
void plotSystem(StarSystem systemToDraw, int systemArrayId){ //draws the white circle images that represent the systems on the map
    StarSystemView viewToDraw = new StarSystemView(this, getResources().getString(systemToDraw.nameId), systemArrayId);

    RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);


    ShapeDrawable myShape = new ShapeDrawable(new OvalShape());

    myShape.setIntrinsicHeight(10);
    myShape.setIntrinsicWidth(10);
    myShape.getPaint().setColor(-1);

    layoutParams.leftMargin = (systemToDraw.coordinates.x - 50) * 4;
    layoutParams.topMargin = (systemToDraw.coordinates.y - 50) * 4;

    viewToDraw.setImageDrawable(myShape);

    viewToDraw.setOnClickListener(this);
    viewToDraw.setFocusable(true);
    viewToDraw.setClickable(true);

    starMap.addView(viewToDraw, layoutParams);
    viewToDraw.bringToFront();
}
 public void onClick(View view){
StarSystemView clickedView = (StarSystemView) view;
    StarSystem systemToView = PlayerCharacterInfo.currentPlayerCharacter.occupiedSector.starSystems[clickedView.systemArrayId];

    systemNameView.setText(getResources().getString(systemToView.nameId));

    switch(systemToView.systemFactionId){
        case 0:
            systemFactionView.setText(getResources().getString(R.string.faction_neutral));
            break;
        case 1:
            systemFactionView.setText(getResources().getString(R.string.faction_imperial));
            break;
        case 2:
            systemFactionView.setText(getResources().getString(R.string.faction_federation));
            break;
        case 3:
            systemFactionView.setText(getResources().getString(R.string.faction_republic));
            break;
    }

    systemCoordinatesView.setText(Integer.toString(systemToView.coordinates.x)+", "+Integer.toString(systemToView.coordinates.y));

    switch(systemToView.numberOfPlanets){
        case 1:
            systemPlanetsNumberView.setText(getResources().getString(R.string.basic_one));
            break;
        case 2:
            systemPlanetsNumberView.setText(getResources().getString(R.string.basic_two));
            break;
        case 3:
            systemPlanetsNumberView.setText(getResources().getString(R.string.basic_three));
            break;
    }
}

也可供參考imageview類

public class StarSystemView extends ImageView {

String systemName;
int systemArrayId;

public StarSystemView(Context context, String systemNameToSet, int arrayIdToSet){
    super(context);
    systemName = systemNameToSet;
    systemArrayId = arrayIdToSet;
}
}

我嘗試過使用setOnClickListener（StarMapActivity.this）我也試過將StarSystemViews的布局參數設置為12和12而不是包裝內容。 當我在某處閱讀時，我還將交互式視圖放在了焦點上。 我還仔細檢查了Android開發者網站，看看我是否無法弄清楚我是否犯了任何拼寫錯誤或編碼錯誤。

開始懷疑可縮放布局內的圖像視圖是否完全無法點擊。
在此先感謝您的幫助。

更新：您只是在畫布的繪制中縮放布局，而不是通過移動和縮放其中的實際視圖。 因此，在縮放它們的那一刻，您將無法單擊，因為視圖不在其被繪制的位置。 你將不得不以不同的方式進行擴展，你應該發布一個新的問題，以獲得有關如何的建議。
