我需要动态生成一些图块(垂直LinearLayout)。在每个图块的内部,左侧都有一个图像,右侧有一些文本,例如温度,湿度和状态。图像,文本和图块的数量可以在运行时更改。
我设法生成了图块,但没有找到有关如何向其添加内容的解决方案。有人可以告诉我正确的方法吗?
ScrollingActivity.java
public class ScrollingActivity extends AppCompatActivity {
private LinearLayout myLayout;
Context ctx;
DynamicLayout DynLay;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_scrolling);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
myLayout = (LinearLayout) findViewById(R.id.linLayout);
DynLay = new DynamicLayout(ctx);
// Add some Tiles
for(int i=0; i<10; i++) {
myLayout.addView(DynLay.addTile(getApplicationContext(), "Tile " + i));
}
}
DynamicLayout.java
public class DynamicLayout {
Context ctx;
public DynamicLayout(Context ctx){
this.ctx = ctx;
}
public LinearLayout addTile(Context context, String text){
// Tile
LinearLayout.LayoutParams LinParams = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, 150);
LinParams.setMargins(0, 3, 0, 3);
LinearLayout Tile = new LinearLayout(context);
Tile.setLayoutParams(LinParams);
Tile.setOrientation(LinearLayout.VERTICAL);
Tile.setBackgroundColor(Color.rgb(208,226,217));
// Content of Tile
// ... HOW TO ADD SOME CONTENT???
return Tile;
}
