Alternative method for TextView.getMaxLines () for Android 4.0.3 (API 15) and below

I fall under crash logs when using the getMaxLines() method of Texview on Ice Cream Sandwich Android 4.0.3 version,

So, I realized that my application has a lower sdk that does not have this getMaxLines () method.

How to remove this failure. I did not find alternative methods

getMaxLines () TextViewCompat looks like the right solution for this.

You can also look in SourceCode in TextViewCompat and copy the functions you need.

Code:

 int maxLines = TextViewCompat.getMaxLines(yourtextView);

instead:

 int maxLines = yourtextView.getMaxLines();

I highly recommend using lib and TextViewCompat support. But just for completeness, there is also a (current) source TextViewCompatDonut getMaxLines :

 static int getMaxLines(TextView textView) { if (!sMaxModeFieldFetched) { sMaxModeField = retrieveField("mMaxMode"); sMaxModeFieldFetched = true; } if (sMaxModeField != null && retrieveIntFromField(sMaxModeField, textView) == LINES) { // If the max mode is using lines, we can grab the maximum value if (!sMaximumFieldFetched) { sMaximumField = retrieveField("mMaximum"); sMaximumFieldFetched = true; } if (sMaximumField != null) { return retrieveIntFromField(sMaximumField, textView); } } return -1; }

Try it, it can help,

  TextView t1 = (TextView) findViewById(R.id.txt1); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) { int no= t1.getMaxLines(); Log.e("No of Lines: ", String.valueOf(no)); }
