如何通过代码设置TextView的layout_gravity？

我尝试使用layoutparams而没有任何好结果。

new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.FILL_PARENT, Gravity.LEFT | Gravity.CENTER_VERTICAL);

使用完之后，我的文字就会停留在左上角的标准位置。宽度：FILL_PARENT或重力代码都不做任何事情。

Answer 1

FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.LEFT | Gravity.CENTER_VERTICAL)

Answer 2

您可以使用以下代码在代码中使用重力：

    Button button = (Button) findViewById(R.id.MyButtonId);
    // need to cast to LinearLayout.LayoutParams to access the gravity field
    LayoutParams params = (LayoutParams)button.getLayoutParams(); 
    params.gravity = Gravity.BOTTOM;
    button.setLayoutParams(params);

Answer 3

 layout = (LinearLayout) findViewById(R.id.vendor_detail_lay);
    LinearLayout linearLayout = new LinearLayout(getApplicationContext());
    linearLayout.setOrientation(0);
    txtveiw = new TextView(NewVendorDetailActivity.this);
    txtveiw.setLayoutParams(Gravity.LEFT | Gravity.CENTER_VERTICAL);
    txtveiw.setId(itemId);
    txtveiw.setText(cursor.getString(cursor.getColumnIndex(DataBaseHelper.KEYNAME)));

    linearLayout.addView(txtveiw);
    layout.addView(linearLayout);

Answer 4

Android set the gravity for a TextView programmatically 你看到过这个回应吗？

TextView tv  = (TextView) findViewById(R.layout.text_view);   
tv.setGravity(Gravity.CENTER | Gravity.BOTTOM);

Answer 5

保持现有布局参数的最佳解决方案：

您需要使用父布局的LayoutParams（因此布局_ 重力）

例如，如果父是FrameLayout do：

FrameLayout.LayoutParams layoutParams = 
    new FrameLayout.LayoutParams(textView.getLayoutParams());
layoutParams.gravity = Gravity.BOTTOM | Gravity.RIGHT;
textView.setLayoutParams(layoutParams);
