尝试这种方式：

1。 Xml文件（activity_main.xml）

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/lnrMain"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"/>

2。 Java文件（MainActivity.java）

public class MainActivity extends Activity {

private LinearLayout lnrMain;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    lnrMain = (LinearLayout) findViewById(R.id.lnrMain);
    for (int i=1;i<5;i++){
        LinearLayout layout = new LinearLayout(this);
        layout.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT));
        layout.setId(i);
        TextView textView = new TextView(this);
        textView.setText("Linear Layout "+i);
        textView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.MATCH_PARENT));
        layout.addView(textView);
        layout.setTag(i);
        layout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(MainActivity.this,"Linear Layout "+view.getTag()+" Is Clicked...",Toast.LENGTH_SHORT).show();
            }
        });
        lnrMain.addView(layout);
    }
  }
}

点击Android，动态获取线性布局的ID
